Options
- ABoth and are true, and is the correct explanation for A.
- BBoth A and R are true, but R is not the correct explanation for A.
- CA is true, but R is false.
- DA is false, but R is true.

A. Both and are true, and is the correct explanation for A.
Step-by-step solution
- Assertion (A) is true; one mole of any ideal gas occupies 22.4 liters at STP.
- Reasoning (R) is true because this volume results from the ideal gas law .
- Therefore, the correct option is A) Both and are true, and is the correct explanation for A.
