   A developer's code contains `x = ( 1 + 2 ) * 3` and `if (x == 4) is True:`. The team's CI runs `pycodestyle` and `pylint`. Which issues will these tools flag, and what is the correct fix?

   • A`pylint` will flag C0326 (bad whitespace) and C0121 (singleton comparison); fix by removing spaces and using `if x:`.
   • B`pycodestyle` will flag E201/E202 (spaces inside parentheses) and E712 (comparison to True); fix by removing the spaces and using `if x == 4:`.
   • C`pycodestyle` will flag E501 (line too long) and E711 (comparison to None); fix by splitting the line and using `is None`.
   • DBoth tools will flag the code as correct because the syntax is valid.
