None of these options seem right to me.

Wait, so y is still accessible? That's interesting!

I thought it would be private?

I'm confused about this one. I thought protected members could be accessed in derived classes, but I don't remember if that applies here.

This seems similar to a practice question we did on inheritance. I think "y" remains protected, but I might be mixing it up with another example.

I remember something about access specifiers, and I feel like "y" should be accessible in class B, but I can't recall if it changes to private.

I think "y" is protected in class B since it inherits from class A, but I'm not entirely sure how that affects access.

Hmm, I'm not entirely confident about this one. I'll need to review the access modifier rules for inheritance to make sure I'm not missing anything.

I've got this! Since 'y' is declared as protected in class A, and class B inherits publicly from A, 'y' will be accessible as protected in class B. The answer is C.

I'm a bit unsure about this one. The access modifiers can get confusing, especially when dealing with inheritance. I'll need to double-check the rules to be sure.

Okay, let me think this through step-by-step. Class A has a protected member 'y', and class B inherits publicly from A. So 'y' should be accessible in B, right?

Hmm, this looks like a tricky inheritance question. I'll need to carefully consider the access modifiers to determine the visibility of the variable 'y' in class B.

I'm pretty sure option D is not the right answer here. Locating the email sends in the Tracking tab within Email Studio won't give me the list of subscribers I need. I think I'll go with either option A or C, depending on how comfortable I feel with the criteria.

Based on my understanding of Okta's capabilities, SAML is definitely a supported SSO protocol in their integration network. I'll select 'Yes' for this.

I'm a bit confused by this question. Acquiring a golf club overseas seems like a really big move for a club that's struggling with cash flow. I think I'd focus on the more straightforward options like the free trial or the referral program.
