Solution
The correct option is B Isobaric
Given that, the P−V indicator diagram shows a straight line parallel to the volume axis.
The pictorial representation is as shown below.
Finding the slope of the graph, we get
ΔPΔV=0
⇒ΔP=0
Hence, we can say that pressure remains constant.
We know that, if pressure remains constant during a process, we call it as an isobaric process.
Thus, option (b) is the correct answer.
