Arrange the following groups in correct activating order towards electrophilic aromatic substitution reaction $\left(\mathrm{EAS}\right)$ :-

Consider the following reaction sequence,

${\mathrm{CH}}_3\mathrm{C}\equiv \mathrm{CH}\underset{ 2 \mathrm{mole}}{\stackrel{ \mathrm{Hcl} }{⟶}}\mathrm{A}\underset{ \mathrm{Heat} }{\stackrel{ \mathrm{aq}.\mathrm{KOH} }{⟶}}\mathrm{B}$

The products $\left(\mathrm{A}\right)$ and $\left(\mathrm{B}\right)$ are, respectively,

In the following reaction sequence

$\mathrm{Ph}-\mathrm{C}\equiv \mathrm{CH}\frac{\mathrm{aq}·{\mathrm{H}}_2{\mathrm{SO}}_4}{{\mathrm{Hg}}^{2+}}\mathrm{A}\frac{1.{\mathrm{CH}}_3\mathrm{Mgl}}{2.{\mathrm{H}}_2\mathrm{O}}\mathrm{B}$

the product $\left(\mathrm{B}\right)$ is :
