Helena is studying functional programming, using the drawImages template shown in the accompanying figure as an example. She comes to you for help in learning the key features of functional programming.
-Helena has heard that every recursive function contains a base case that represents a stopping condition. In the drawImages template, you explain to her that the function would reach the base case when _____.
A) $imgCount < 0 
B) $imgCount = 0 
C) $imgCount - 1 > 0 
D) $imgCount = ""

In the drawImages template, the recursive function calls itself while subtracting 1 from the $imgCount variable. The base case occurs when $imgCount reaches 0, indicating that all the images have been drawn. Therefore, the correct option is B.
