Wait, is C even a valid expression?

D should be True, right?

C seems off, not sure about that one.

I have a feeling that option C is incorrect because has_attr usually checks for attributes, not methods like 'get'.

I'm a bit confused about option B. I thought class variables were accessed differently, but I can't recall the exact syntax.

I remember practicing a similar question where we had to check instance types. I feel like option D could be true if obj_c's get method returns the right value.

I think option A might be true since obj_b is an instance of C, but I'm not completely sure.

This is a tricky one, but I'm feeling pretty confident. I'll start by analyzing the class structure and then see which of the given expressions match up with the code. Gotta be careful not to overthink it.

Okay, I think I've got this. The key is to focus on the relationships between the objects and the class attributes. If I can identify the correct instances and class variables, I should be able to determine the true expressions.

I'm a bit confused by the syntax in the code snippet. I'll need to double-check my knowledge of Python's class and object syntax to make sure I understand what's going on before I can confidently select the right answers.

Hmm, this looks like it's testing our understanding of class attributes and object instances. I'll need to carefully read through the code and options to determine which expressions evaluate to True.

I'm not sure about option D, but I think option B might also evaluate to True because it compares a private variable in class C.

This is a tricky one, but I think the key is understanding how Python's name mangling works. B and D are the way to go, in my opinion.

Ha! This question is a bit of a gotcha. I bet the exam writer is trying to trip us up with that private variable access. I'll go with C and D to play it safe.

Hmm, I'm not sure about B. Isn't accessing private variables a bit of a code smell? I'd go with C and D as the correct answers.

I agree with An. Option A checks if obj_b is an instance of class C, and option D checks if obj_c.get() returns 2.

I think B and D are the correct answers here. C's private variable _VarA is being accessed correctly, and obj_c's get() method returns 2, so those expressions should evaluate to True.

Yes, accessing C's private variable and obj_c's method return value of 2.
