Directions: There are two statements, one labeled the Assertion (A) and the other labeled the Reason (R). Examine the statements and decide if the Assertion A and Reason R are individually true and if so, whether the reason is the correct explanation of the assertion. Select your answers to the question from the codes given below:

Assertion (A): It is easier to swim in sea water than in the river water. Reason (R): Sea water is heavier and the immersed portion of the body experiences a greater upward thrust.

  1. Both A and R are true and R is the correct explanation of A

  2. Both A and R are true and R is not the correct explanation of A

  3. A is true but R is false

  4. A is false but R is true

Sea water has a higher density than river water due to dissolved salts. According to Archimedes' principle, a denser fluid exerts a greater buoyant force (upward thrust) on an immersed object, making it easier to float or swim.
