• A. $A-r$, $B-q$, $C-p$, $D-s$
• B. $A-r$, $B-s$, $C-q$, $D-p$
• C. $A-r$, $B-s$, $C-p$, $D-q$
• D. $A-p$, $B-q$, $C-r$, $D-s$

Answer 1

Answer: (B)

Conversion of a liquid into solid is fusion.
$A\to r$
Conversion of a liquid into vapour is vaporisation.
$B\to s$
Conversion of a solid into vapour directly is sublimation.
$C\to q$
Melting of ice caused by pressure is regelation.
$D\to p$
