Sucrose gives a negative result with Benedict's solution, but gives a positive result when it is first boiled with dilute $HCl$ and then neutralised. The reason is that

Asucrose is converted to a ketone
Bhydrolysis gives glucose and fructose, which are reducing sugars
Cacid oxidises sucrose to an aldehyde
Dhydrolysis gives a non-reducing polysaccharide

Answer: B

In sucrose the anomeric carbons of glucose and fructose are joined through the glycosidic link, so no free aldehyde or hemiacetal group exists and it does not reduce Benedict's solution. Acid hydrolysis frees glucose and fructose, both of which are reducing.
