The correct answer is: option (a) i.e. (a)  tB = tC = tD
Since when we calculate the relative velocity of a particle with respect to another particle along the same line, then the particles can never have an equal velocity and therefore the time taken by the particles will be different and not same. Therefore, all the particles will reach at different time interval. So statement (a) is incorrect.
