B.
Reducing pressure to one fourth at constant temperature
Answer
C.
Reducing temperature to one fourth at constant pressure
D.
Reducing the temperature to half and doubling the pressure

Answer: Option B

Solution

Answer: Option B
Solution:
According to the gas law we can write
So by reducing the pressure to at constant temperature the volume increases to times the initial volume.
