C makes the most sense to me!

I always thought it was D.

Wait, are you sure about that?

Definitely C! Blocks can nest anywhere.

I think it's C, right?

I’m leaning towards option D because I recall something about Blocks not being able to include themselves directly.

I feel like option C sounds right, but I’m a bit confused about the self-referencing part.

I remember practicing a question like this, and I think the answer was about Blocks being able to nest inside other Blocks too.

I think Blocks can be used inside Screens, but I'm not sure if they can reference themselves.

I've got a good strategy for this. I'll eliminate the options that don't make sense, then choose the one that seems most logical. Let me think this through...

Okay, let me break this down. A Block can't be used only inside other Screens, that's option A. And it can't be used only inside other Blocks, that's option B. So I'm leaning towards C or D.

Hmm, I'm a bit unsure about this. I'll have to think it through carefully. Is it possible for a Block to be used inside itself?
SH

I'm pretty confident about this one. I think the answer is C - Blocks can be used inside Screens and Blocks, including itself.

Okay, I think I've got this. The Payment class is an abstract class, so the CreditCardPayment class needs to extend it and override the makePayment method. Option A looks like the correct implementation to me.

I'm stumped on this one. Maybe I need to take a break and come back to it. All these Blocks are making my head spin!
FR

Taking a break might help clear your head, but Blocks can be used in a few different places.
DY

Yeah, just remember that Blocks can be pretty versatile in where they can be used.
JA
Janey

Don't worry, Blocks can be used inside Screens and Blocks, including itself.

Haha, imagine a Block inside a Block inside a Block. It's Blocks all the way down! I'm gonna go with C, seems the most comprehensive option.
JE
Jenifer

I can't even imagine how complex it would be to have a Block inside a Block inside a Block. C definitely seems like the right answer.
JU
Judy

Yeah, C does seem like the most versatile choice. It covers all the possibilities.
BE

I know right, it's like a never-ending puzzle of Blocks within Blocks.
CH
Cherry

I'm going with D. Blocks shouldn't be able to be used on themselves, that would just be confusing and lead to weird nesting issues.
EU
Eun

I'm not sure, but I think a Block can only be used inside other Blocks.
FR
Freida

I agree with Silva, because Blocks can be nested within other Blocks and Screens.
RO

Option C makes the most sense to me. Blocks should be able to be used inside other Screens and Blocks, including itself. That's the flexibility I'd expect from a feature like this.
AN
Andra

I think option C is the most logical one as well. It allows for more flexibility in designing the interface.
JO
Josephine

I agree, option C seems like the most versatile choice.
SI
