What path should I take?

GCSE: A*AABBBBBCCCD (B+ in M,E,C,B,P)
AS: ABBB (99% Maths, 79.5% English, 77% Chemistry, 70% Psychology)

Anticipated course: MMath
Anticipated university: Any RG
Future plans: Conversion to Law post-degree

A2 LEVEL OPTIONS
PATH 1:
Maths, English, Chemistry, Psychology
PATH 2:
Maths, Further Maths AS, Further Maths A2, Chemistry
PATH 3:
Maths, Further Maths AS, Further Maths A2, English

In my shoes, which path do you think would be the most sensible to take?

Path 2 or 3, I'd say you would be missing a trick not taking further maths. I'd probably err on the side of Path 2 because Chemistry would complement your maths subjects quite well, you got a high B (like me!) which could become an A/A* depending on circumstances. Once you get a degree the lack of A-level English shouldn't matter for law if I'm not mistaken. My humble opinion anyway

Thanks for the advice!!

No problem, that's one heck of a maths score!
