\sin \left(2 \cos ^{-1}\left(\cot \left(2 \tan ^{-1} x\right)\right)\right)=0, x > 0

, then which of the following is incorrect?

View answer and explanation

Correct option: C

x=3

Option B (I, II, III only) is correct because the given conditions lead to (I-A)(I-B) = 0, implying that |I-A| = 0 and |I-B| = 0, and A+B = AB+I.
