Answer 1

The correct option is A (a - p), (b - q), (c - q, s), (d - q, r)

"Wood alcohol" is methanol $C{H}_3-OH$.
It acquired this name because it was once produced chiefly as a byproduct of destructive distillation of wood.
"Grain alcohol" is a purified form of ethyl alcohol (ethanol$-C{H}_3-C{H}_{2}OH$) made from distillation of fermented grain. It is produced by fermentation of sugars in grain by yeast.
"Rectified Alcohol" is also ethanol of agricultural origin, but is highly concentrated by process of repeated distillation, a process called rectification.
"Power Alcohol" is ethyl alcohol used to generate power, for example, as an additive to motor fuels to act as a fuel for internal combustion engines. It has $80$% petrol and $20$% alcohol.
Thus option (A) is correct answer.
