Final answer:
c.) the board position; for example, def(col, row):In a tic-tac-toe program, the function to select a column and row would need the board position as input arguments, defined as def turn(col, row),
Step-by-step explanation:
When implementing a function to facilitate players selecting a column and row in a tic-tac-toe program, the function would most likely need the board position as input arguments. This would be option C: the board position; for example, def turn(col, row).
The reasoning for this choice is that each player's turn in tic-tac-toe involves choosing a specific column and row on the board to place their mark (either 'X' or 'O'). The function would also implicitly or explicitly need to know which player is taking the turn to update the board accordingly.
However, since the function specifically asks for ‘selecting a column and row,’ the essential arguments are col (column) and row (row) indicating the desired cell on the tic-tac-toe board where the player intends to make their move.
