Question

Assertion (A): All squares are rectangles.

Reason (R): All rectangles have four right angles.

Choose the correct option:

  1. A. Both A and R are true and R is the correct explanation of A
  2. B. Both A and R are true but R is not the correct explanation of A (Correct answer)
  3. C. A is true but R is false
  4. D. A is false but R is true

Correct Answer

Option B — Both A and R are true but R is not the correct explanation of A

Detailed Solution & Explanation

The correct answer is Both A and R are true but R is not the correct explanation of A.

Key Points

  • A is true (squares satisfy all rectangle conditions). R is true.
  • But R does not fully explain A - squares also need equal sides, not captured by R alone.
