Need help picking a fourth A level?

So I enrol at a sixth form college in a couple of hours and have chosen to study English literature, history, psychology and either sociology, law or economics.

I want to study either English or psychology at degree level and am better at essay based subjects. What should I pick as a fourth Alevel: sociology, law or economics?

What are your other 3? In terms of the most respectful, it would be economics. Sociology and Law are weaker A Levels. But if your other 3 are facilitating, then doing one slightly weaker one shouldn't do too much harm.

So far I've got english literature, history and psychology
