LLD - Design — Chess GameWhich of the following is the correct way to represent a move validation function signature in Python?Adef validate_move(start_pos: str, end_pos: str) -> bool:Bdef validate_move(start_pos, end_pos): return intCfunction validate_move(start_pos, end_pos) { return true; }Ddef validate_move(start_pos: int, end_pos: int) -> str:Check Answer
Step-by-Step SolutionSolution:Step 1: Identify correct Python function syntaxPython uses def keyword, type hints with colon, and returns bool for validation.Step 2: Check each optiondef validate_move(start_pos: str, end_pos: str) -> bool: matches Python syntax and returns bool. Others have wrong return types or language.Final Answer:def validate_move(start_pos: str, end_pos: str) -> bool: -> Option AQuick Check:Python function signature with bool return = def validate_move(start_pos: str, end_pos: str) -> bool: [OK]Quick Trick: Use def with type hints and bool return for validation [OK]Common Mistakes:Mixing Python and JavaScript syntaxWrong return type in signatureMissing colon or parentheses
