Answer:

B. 6

Read Explanation:

sec2A=1+tan2Asec^2A=1+tan^2A

cosec2A=1+cot2Acosec^2A=1+cot^2A

2(1+tan2A)+4(1+cot2A)2tan2A4cot2A2(1+tan^2A)+4(1+cot^2A)-2tan^2A-4cot^2A

2+2tan2A+4+4cot2A2tan2A4cot2A2+2tan^2A+4+4cot^2A-2tan^2A-4cot^2A

(2+4)+(2tan2A2tan2A)+(4cot2A4cot2A)(2+4)+(2tan^2A-2tan^2A)+(4cot^2A-4cot^2A)
