In the reaction :
$\mathrm{C}+4 \mathrm{HNO}_{3} ightarrow \mathrm{CO}_{2}+2 \mathrm{H}_{2} \mathrm{O}+4 \mathrm{NO}_{2}$
$\mathrm{HNO}_{3}$ act as
  1. an oxidizing agent
  2. an acid
  3. an acid as well as oxidizing agent
  4. a reducing agent

Solution

O.N. of $\mathrm{C}$ changes form 0 to $+4$ by oxidation. Hence $\mathrm{HNO}_{3}$ is oxidising agent.
