x = xosin2(wt)
x = xo(1 – cos2wt)/2
So x = xo/2 – (½)xocos(2wt)
SO its amplityde is xo/2
and 2w = 2pi/T
So T = pi/w.
So correct option is (4).
Hopeit clears. If you like anser then please approve it.

Dear student,
Please find the answer to your question.
 
x = xosin2(wt)
x = xo(1 – cos2wt)/2
So x = xo/2 – (½)xocos(2wt)
Hence its amplitude is xo/2
and 2w = 2pi/T
=> T = pi/w.
Hence, correct option is (4).
 
Thanks and regards,
