A ball is projected from origin at time ...

A ball is projected from origin at time t= 0. The x and y coordinates of its displacement are given by `(x = 4t^2)` and `y = (3t - 5)`. Then its instantaneous velocity at any time t is

`(8 hati + 3 hat j)`

`(8t hat i + 3 hat j)`

`(4t hati - 5 hat j)`

`(4 hati - 3 hat j)`
