`y(x, t) =(0.8)/([(4x + 5t)^(2) +5])` represents a moving pulse where `x` and `y` are in metre and `t` in second. Then,choose the correct alternative(s):  (a) pules is  moving in positive x- direction  (b) in `2 s` it will travel a distance of `2.5 m`  (c) its maximum displacement is `0.16 m`  (d) it is a sysmmetric pulse
