The governing differential equations connecting the output y(t) and the input x(t) of four continuous time systems are given in the List I and List II respectively. Match list I (Equation) with List II (System Category and select the correct answer using the code given below :
List I
A. 2tdy/dt + 4y = 2tx
B. ydy/dt + 4y = 2x
C. 4d2y/dx2 + 2 dy/dt + y = 3 dx/dt
D. (dy/dt)2 + 2ty = dx/dtList II
