Assertion: Bulk modulus of elasticity \( (\mathrm{K}) \) represents incompressibility of the material.
P
Reason: Bulk modulus of elasticity is proportional to
W
change in pressure.
(1) If both assertion and reason are true and the reason is the correct explanation of the assertion.
(2) If both assertion and reason are true but reason is not the correct explanation of the assertion.
(3) If assertion is true but reason is false.
(4) If the assertion and reason both are false.
