Correct option is A
Solution:
Option A(first graph) is correct.
Let's compare it properly:
From the given block graph:
0 to 1 Height = 1 Area = 1
1 to 2 Height = 2 Area = 2
2 to 3 Height = 0.5 Area = 0.5
Thus cumulative area is:
At x = 0 0
At x = 1 1
At x = 2 3
At x = 3 3.5
Now look at Option 1 (your selected option):
From 0 to 1 gradual linear rise (correct, because area is increasing uniformly when height is constant)
From 1 to 2 steeper rise (correct, because height is more = 2)
From 2 to 3 slower rise (correct, because height is only 0.5)
So Option A (Graph 1) is actually correct!
Final Final Answer:
Option A (first graph)
