Which gas turns blue cobalt chloride paper light pink?

An organic compound (A) on heatig produces two gases (B) and (C) and neutral oxide (D) which turns cobalt chloride paperr pink. Gas (B) turns lime water milky and produces an acidic solution with water. Gas (C) produces a poisonous gas (E) with chlorine gas, the gas, this gas with ammonia gives an organic compound (F) which on further reaction with (D) gives NH_(3) gas. Then, compound (A) and (F) can be found as:
