When $1:2$ equivalence ratio of the gases $X$ and $Y$ are heated to $573 \ K - 673 \ K$ at $200-300 \ atm$ in the presence of $ZnO-Cr_2O_3$ catalyst,methanol is formed. Here,the gases $X$ and $Y$ are $X$ and $Y$ respectively.

• A
  $CO_2$ and $H_2$
• B
  $CO$ and $H_2$
• C
  $CH_4$ and $O_2$
• D
  $CH_4$ and $H_2O_{(g)}$
