Which of the following is not an activated nickel catalyst preparation

1.	Which of the following is not an activated nickel catalyst preparation reaction?(a) Ni(OH)2 + H2→ Ni+H2O(b) Ni(CO)4 → Ni + 4CO(c) 2Al·Ni + 6NaOH → Ni + 2NaAlO3 + 3H2(d) NiCO3 + H2→ Ni+H2O + CO2This question was addressed to me in an online quiz.I'm obligated to ask this question of Natural Products topic in division Natural Products of Chemical Technology
Answer» Correct option is (B) Ni(CO)4 → Ni + 4CO To elaborate: (OH)2 + H2 → Ni+H2O,2Al·Ni+6NaOH → Ni + 2NaAlO3 + 3H2, NiCO3 + H2 → Ni + H2O + CO2 arereactions of producing ACTIVATED nickel catalyst WHEREAS Ni(CO)4 → Ni + 4CO is an equilibrium reaction.
