On reductive ozonolysis yields

A.6-oxoheptanal✓ Correct
B.6-oxoheptanoic acid
C.6-hydroxyheptanal
D.3-hydroxypentanal
Explanation

When the alkene undergoes reductive ozonolysis, it will form aldehydes, ketones or the compounds having both aldehyde and ketone. So, in the reactant given when the double bond breaks, then at first position aldehyde group will form and at the sixth position ketone group will form. Hence, there will be formation of 6- oxoheptanal. The reaction is given below:
