Yes, C is correct answer because,

1. The aggregate in which pores are filled with some moisture and having surface dry is called Dry Aggregate.

2. The aggregate in which pores are filled with no moisture and having surface dry is called Very Dry Aggregate.

3. The aggregate in which pores are filled with full moisture and having surface just wet is called Moist Aggregate.

4. The aggregate in which pores are filled with full moisture and having surface just dry is called Aggregate.

No, it's wrong.

If the aggregate contains some moisture in the pore and has surface dry is called dry aggregate while the aggregate pores filled completely with water and having surface dry is called SSD aggregate. That's the difference

So, Option C is correct.

Ref: RS Khurmi.

Saturated surface dry (SSD) is defined as the condition of an aggregate in which the surfaces of the particles are "dry" (i.e, surface adsorption would no longer take place), but the inter-particle voids are saturated with water.

So the given answer is right.

It's dry aggregate because when the press are completely filled with water it is saturated surface dry but here the just gave the pores have moisture so I think it's dry aggregate.

@All.

Given option is right. Moisture is some pores called Dry aggregate & in all pores called saturated surface dry aggregate. In question it said moisture in all pores.

Answer is dry aggregate. In saturated surface dry aggregate all the pores are completely filled with water but having their surface dry.

Given answer D is correct.

I agree with the given answer.

In my opinion, the correct answer is C.

Given option is right. I agree with it.

I think the correct answer is C.
