S = A( 1 - e^-Bxt )
where S is speed
t is time and x is the displacement .
we know,
exponential function have no units so,
-Bxt is unitless quantity. but this is possible only when ,
unit of B × unit of xt = unitless { Let 1
unit of B = 1/unit of xt
unit of B = 1/m.s
unit of B = m-¹.s-¹
hence, option (A) is correct
