Answer: B
Correct answer: evidence produced in court was
Evidence is uncountable in English: it has no plural, so evidences is wrong, and it takes a singular verb, so were is wrong too. Both faults must be corrected together. To refer to separate items one says pieces of evidence or items of evidence. It belongs to the group of nouns that are uncountable in English although countable in many Indian languages, and the whole set is worth learning: information, advice, furniture, luggage, baggage, machinery, stationery, equipment, scenery, poetry, bread, news and work. None takes an -s, none takes a or an, and all take singular verbs. They are quantified with much and less rather than many and fewer: much evidence, less information.
