Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R :

Assertion A : Helium is used to dilute oxygen in diving apparatus.

Reasons R : Helium has high solubility in O\(_2\).

In the light of the above statements, choose the correct answer from the options given below :

1. A is false but R is true.

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

3. Both A and R are true and R is NOT the correct explanation of A.

4. A is true but R is false.

Answer: 4. A is true but R is false.

Key idea: Gases dissolve in blood at high pressure; helium is chosen because it is hardly soluble.

Assertion A is true: divers breathe an oxygen-helium mixture. Reason R is false: helium has very low solubility in blood (and does not cause the bends or narcosis as nitrogen does). Option 4: A true, R false.
