Which of the following is not an isotope of hydrogen?

Given below are two statements :
Statement-$I$: Methane and steam passed over a heated $Ni$ catalyst produces hydrogen gas.
Statement-$II$: Sodium nitrite reacts with $NH_4Cl$ to give $H_2O$,$N_2$ and $NaCl$.
In the light of the above statements,choose the most appropriate answer from the options given below :

Action of water or dilute mineral acids on metals can give

Consider the following statements:
$1.$ Atomic hydrogen is obtained by passing hydrogen through an electric arc.
$2.$ Hydrogen gas will not reduce heated aluminium oxide.
$3.$ Finely divided palladium adsorbs large volume of hydrogen gas.
$4.$ Pure nascent hydrogen is best obtained by reacting $Na$ with $C_2H_5OH$.
Which of the above statements is/are correct?

Match List $I$ with List $II$

List $I$	List $II$
$A.$ Cobalt catalyst	$I.$ $(H_2 + Cl_2)$ production
$B.$ Syngas	$II.$ Water gas production
$C.$ Nickel catalyst	$III.$ Coal gasification
$D.$ Brine solution	$IV.$ Methanol production

Choose the correct answer from the options given below:

Give the reaction of methane with steam for the production of dihydrogen.
