The ____________ function removes the first element of a set and the last element of a list. Select one: a. remove b. discard c. dispose d. pop

The correct answer to the question is d. pop.

In programming, particularly in languages like Python, the pop function is used to remove elements from data structures. For a set, it removes an arbitrary element (since sets are unordered), while for a list, it removes and returns the last element by default unless an index is specified.

Here’s a brief overview of the other options:

• a. remove: This typically removes a specified element from a list or set but does not affect the first or last position specifically.
• b. discard: Used in the context of sets, it removes a specified element without raising an error if the element is not found, but does not refer to lists at all.
• c. dispose: This is not a standard method in the same context and does not apply to the removal of elements from lists or sets.

Thus, the only option that accurately fits the description is "pop."
