$(a)$ $R_2SiO$ is repeating unit of linear silicones

$(b)$ $R$ $SiCl_3$ on hydrolysis followed by dehydration gives linear silicones

$(c)$ Silicones can be used as heat insulator

$(d)$ Silica is soluble in $HF$

The correct statement$(s)$ is/are

$HC \equiv CH\,\xrightarrow[{H{g^{2 + }}}]{{{H_2}S{O_4}}}\,'P'$

Product $'P'$ will not give
