Definition: rhombus is a quadrilateral with all four sides equal in length.

(1) Quadrilateral q has four equal sides --> quadrilateral q is a rhombus. Sufficient.

(2) Quadrilateral q has four equal angles. Quadrilateral q could be a rectangle (which is not a square, thus not a rhombus) as well as a square, thus a rhombus. Not sufficient.

Hope it helps.

But a square can also have all equal sides so how can statement A is sufficient?

All squares are rhombuses, thus if q is a square then it's a rhombus too.
