   You are refactoring a module where a function definition and a function call both exceed 79 characters. The function has parameters `alpha`, `beta`, `gamma`, and `delta`. You want to keep the code PEP 8 compliant and make future parameter additions produce minimal diffs. Which approach should you take?

   • AFormat the definition with one parameter per line but keep the call on one line with `# noqa: E501`.
   • BFormat both with one parameter per line but omit the trailing comma to keep the code shorter.
   • CFormat both the definition and the call with one parameter per line, indented by 4 spaces, with a trailing comma after the last parameter/argument.
   • DUse a backslash to continue both the definition and the call, keeping all parameters on one logical line.

   A junior developer wrote `def calculate( x , y=2 ):` and `result = calculate( 5 , y=3 )`. Which whitespace correction should you apply to comply with PEP 8?

   • ARemove the space after the comma but keep spaces inside the parentheses: `def calculate( x,y=2 ):`.
   • BKeep the spaces inside the parentheses but remove the space after the comma: `def calculate( x ,y=2 ):`.
   • CRemove spaces immediately inside the parentheses and after the comma: `def calculate(x, y=2):` and `result = calculate(5, y=3)`.
   • DAdd spaces around the equals sign in the default argument: `def calculate(x, y = 2):`.
