Question

Assertion (A) In alumino thermite process, the metals like iron melts due to the heat evolved in the reaction.
Reason (R) The reaction like
$Fe _{2} O _{3}+2 Al \longrightarrow Al _{2} O _{3}+2 Fe$
is highly exothermic in nature

• A. Both $A$ and $R$ are correct; $R$ is the correct explanation of $A$.
• B. Both $A$ and $R$ are correct; $R$ is not the correct explanation of $A$.
• C. $A$ is correct; $R$ is incorrect.
