Answer 1

D. Lithium

Hope it helped.

Answer 2

Answer: Option (d) is the correct answer.

Explanation:

Spontaneous means the process or reaction that occurs suddenly on its own or a process that needs an initiator.

Whereas non-spontaneous processes are the processes that take time to occur.

Spontaneous combustion requires oxidation of the metal or substance which means there will be loss of electrons.

Therefore, a metal that is most reactive will easily lose electrons.

Thus, we can conclude that out of the given options lithium will easily lose electrons and hence, lithium will show spontaneous combustion.
