> Option D which is carcerulus. It is a type of schizocarp fruit not a nut fruit which consists of a number of one seeded fragments which adhere to the central axis but the walnut is a type of nut fruit. Therefore, this cannot be the right option. It gets eliminated.

> Option C which is Follicle. It is a type of dry unilocular fruit which is formed from one carpel containing two or more seeds in it. This is also not a nut type of a fruit and hence it cannot be the right option and thus it gets eliminated.

> Option B which is drupe. It is a type of fleshy fruit which has exocarp, mesocarp and endocarp. These are also not the nut type fruit due to which this option gets eliminated and this is incorrect one.

> Option A is Nut and this one is the correct one as walnut is a dry nut type fruit, other options are not a type of nut fruits.

Hence, the correct answer is option (A).
