What will be the output of this move validation snippet if the move is invalid?

def validate_move(piece, start, end):
    if piece == 'pawn' and end[1] != start[1]:

Step-by-Step Solution

Solution:

Step 1: Analyze condition for pawn move
Pawn cannot move diagonally unless capturing; here end[1] != start[1] means diagonal move.
Step 2: Check function return for given inputs
Since end[1] (2) != start[1] (1), function returns False.
Final Answer:
False -> Option B
