Nasrin said she would  $\frac{borrow }{A}$ her new  $\frac{movie camera }{B}$ if I  $\frac{wanted }{C}$ to use it  $\frac{on my trip }{D}$ to Europe. 

The answer provided is "A," which refers to the specific condition stated in the sentence. In the context, Nasrin is discussing her conditions for utilizing something related to "borrowing A." This implies that her ability to use whatever she's mentioning hinges on whether she "waited C."

To clarify:

  
• A: This represents the condition or the item Nasrin will borrow.
  
• B: This is another unrelated item.
  
• C: Refers to her action of waiting, which is a prerequisite to borrowing A.
  
• D: Represents another conditional element that is not directly linked to A.

Since the answer focuses on the item being borrowed (A) in relation to her actions and the conditions involved, it is a correct response. Additionally, the other options do not relate directly to the main intention of the statement.
