$(i)$ $C{H_3} - C \equiv C - C{H_3}$
$(ii)$ $C{H_3} - C{H_2} - C{H_2} - C{H_3}$
$(iii)$ $C{H_3} - C{H_2} - C \equiv CH$
$(iv)$ $C{H_3} - CH = C{H_2}$
Product $(A)$ is
$(a)$ $R_2SiO$ is repeating unit of linear silicones
$(b)$ $R$ $SiCl_3$ on hydrolysis followed by dehydration gives linear silicones
