def check_row_win(board):
    for row in board:
        if all(cell == 'X' for cell in row):

BFalse

CNone

DTrue

Step-by-Step Solution

Solution:

Step 1: Analyze the board and function logic
The first row is ['X','X','X'], so all cells equal 'X' is True, function returns True immediately.
Step 2: Confirm function output
Since the first row satisfies the condition, the function prints True.
Final Answer:
True -> Option D
Quick Check:
Row with all 'X' returns True [OK]

Quick Trick: First matching row returns True [OK]

Common Mistakes:

MISTAKES

Ignoring early return
Assuming function checks columns
Expecting False due to other rows
