B is correct because by default a rhombus has four equal sides, and it says it also has four right angles. A is incorrect because it could refer to any rectangle, C is incorrect because parallelograms don't necessarily have four right angles, and D is incorrect because quadrilaterals don't necessarily have four right angles either.
