1-Aminopropan-2-ol, $CH X_{3} - CH (OH) - CH X_{2} - NH X_{2}$ , reacts with $HIO X_{4}$ . The organic products are

Aethanal, methanal and $NH X_{3}$
Bpropanone and methanal
Cpropanal and ammonia
Dethanal and methylamine

Answer: A

An alpha-amino alcohol is cleaved by periodate like a 1,2-diol. The bond between the CH(OH) carbon and the CH2NH2 carbon breaks, giving CH3CHO from the carbinol carbon and HCHO plus NH3 from the aminomethyl carbon, whose nitrogen is lost as ammonia on hydrolysis.
