A body performing non-uniform circular motion experiences linear acceleration `a_r` and tangential accleleration `a_T`, such that `a_r` changes the direction of linear velocity, while `a_T` changes the magnitude of linear velocity. Then the resultant acceleration 'a' in this case is ,

A

`sqrt(a_r^3+a_T^3) `

B

`a= a_r + a_T`

C

`a = sqrt(a_r^2+a_T^2)`

D

`a = sqrt(a_r^2+a_T^2) `
