A compound "A", when reacted with PCl5 and then with ammonia, gives "B". "B" on treatment with bromine and caustic potash produces "C". "C" on treatment with NaNO2 and HCl at C and then boiling produces ortho-cresol. Compound "A" is:
1. o-Toluic acid
2. o-Chlorotoluene
3. o-Bromotoluene
4. m-Toluic acid
D is N-methyl aniline in the given below sequence of reaction:
\(\text A\xrightarrow{\bf\text{ reduction }}\text B\xrightarrow{\bf\text {CHCl}_3\text{/KOH}}\text C\xrightarrow{\bf\text{ reduction }}\text D\)

| 3. | \(\mathrm{CH_3NH_2 }\) |
4. |  |
Select the correct option based on statements below:
| Assertion (A): | Only a small amount of HCI is required in the reduction of nitro compounds with iron scrap and HCI in the presence of steam. |
| Reason (R): | FeCl2 formed gets hydrolyzed to release HCI during the reaction. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
