Which of the following differential equations has y = x as one of its particular solution?
It is given that that y = x
Now, differentiating both sides w.r.t. x, we get,
Again, differentiating both sides w.r.t. x, we get,
Now, substitute the value of 
in the given options, we will see that the differential equation in option (C) is correct.
= -x2 + x2
= 0
