The expansion is about x=0 so you need to use Maclaurin series.

Use your answers to part (a) to help you with that. Have you done it?

No problem.

If you come to a blank where you don't know whether to use Maclaurin or Taylor, ALWAYS choose Taylor.

This is because Taylor expansion is general to any point along the curve x=a whereas Maclaurin expansion is only for x=0 (i.e. Maclaurin is basically Taylor but for x=0). So if you roll with Taylor, you will end up with Maclaurin anyway if your point is x=0 and so you would still get the right answer.

If you use Maclaurin for a point x \neq 0 then you will get the wrong answer.
