Answer:
D
Step-by-step explanation:
Number of chickens (c) is = 4 times number of horses (4h). c = 4h
Parametize C of the line integral as

from 0<=t<1 then

which means by substituting x with e^t and y with and dx with e^t dt we get

by adding exponents

Option 3 is not possible
-60.2 + 32 = -60.2 + 60
And these are not equal
Rest all options have x and are solvable
