Who is a child soldier?

Correct option is A

A child soldier is defined as any person under the age of 18 who is recruited or used by armed forces or armed groups in any capacity, including fighters, cooks, porters, messengers, or for sexual purposes. This definition is recognized by international bodies such as the United Nations (UN) and UNICEF.
Information Booster: Child soldiers are not only those involved in combat. Children can also be used as spies, guards, human shields, or for non-combat roles that support the military operations. The recruitment of children in armed conflict is a violation of international law, including the Optional Protocol to the Convention on the Rights of the Child on the involvement of children in armed conflict (OPAC).
Additional Knowledge:
· Option (b): Incorrect because child soldiering is illegal by default—no distinction needed as “illegally working”.
· Option (c): Too vague—does not specifically address the military or armed group involvement.
· Option (d): Refers specifically to sexual exploitation, which is one aspect of abuse, but not the complete definition of a child soldier.
