Answer:

I think it should be (A) here, because the temperature hasn't been provided here, as in DIBAL-H that is this reducing agent is used specially for reducing functional groups to aldehydes, and this operates at a low temperature of about -78° C.

Because, then the aldehydic group becomes resistive to further reduction to alcohol.

However, since here no, temperature has been provided, I'll assume DIBAL-H to be not special or different than any other reducing agent converting Cyanide to Enamine being a mild reducing agent though, but fully converting the ester linkage to two individual alcoholic groups.

However, if (A) is not the answer and if it'd have been like temperature being -78°C then the product in option (D) will be formed.

As, cyanide will be converted to aldehydic group and the other ester linkage breaking up, one of the aldehydic group will be formed there becoming resistant to further reduction of itself.

Hope this helps you !
