Wait, calling the destructor manually? That seems risky...

I think that's a runtime error.

I feel like it should compile fine, but I'm not completely confident about the memory management aspect.

I practiced a similar question where the destructor was called automatically. I wonder if that changes the outcome here.

I think this might cause a runtime error because the destructor is called explicitly after the object is created.

I remember something about destructors and how they work, but I'm not sure if calling it manually like that is a good idea.

I'm feeling pretty confident about this one. The key is to understand the lifecycle of the `First` object and how the constructor and destructor are interacting with the dynamically allocated memory. I think I can work through this step-by-step and arrive at the correct answer.

Okay, I've got a strategy for this. I need to focus on the memory management aspect - the object is dynamically allocating memory for the `string` pointer, and then the destructor is deleting that memory. I'll need to think about when that memory is being accessed and whether that could cause any issues.

Hmm, I'm a bit confused here. The code is creating an object and then immediately destroying it, but it's also trying to print something. I'll need to think through the order of operations and how that might affect the output.

I think this is a tricky one. The code is creating a `First` object and then immediately calling its destructor, which could lead to a runtime error. I'll need to carefully consider the implications of that.

Hmm, I'm not sure about this one. The code seems to be creating and then immediately destroying the object, so I'm guessing it might be a runtime error. Maybe C is the correct answer?

I’m leaning towards B. There might be a compilation issue.

A seems right. The object should print before deletion.

I think it will print "Text". So, A is my choice.

I agree with C. The destructor is called too soon.

I think the answer is A. It should print 'Text' since we're creating an object of the First class and calling the Print() function.
