I think the Answer is based on the idea that coarse aggregates provide less surface area of contact than the fine particles that provide a higher surface area of contact b/w particles that causes friction.

In course aggregates surface area is less and hence less friction.

Well, I think about adding more water. Lubrication will be more and thus internal friction will be decreased.

Rich mix. Cement makes a paste which decreases the internal friction.

Answer is right, author don't care about concrete strength. We all know more water makes concrete bleeding and more coarse aggregate causes honeycomb.
