  2. 2 (cis and trans)
  3. 3
  4. 4
Show answer and solution

Correct answer: B. 2 (cis and trans)

M(AA)₂B₂-type octahedral complex has cis and trans forms. Additionally, the **cis** isomer is chiral and itself exists as a pair of enantiomers (d/l) — though the question asks only for geometric isomers, the answer is **2** (cis, trans).
