In which field should I pursue MBA after completing English (H)?

It depends on where you want to go, really. If you feel your quantitative skills are on the weaker side, avoid finance and operations at all costs. For somebody who isn't good at math, sitting a finance test is somewhat like facing Brett Lee on a green pitch. Unplayable. Marketing is pretty interest

Hello! Go for any field you have deep interest in. But I would like to suggest you to go for HR if you have good communication skills. All the best.
