Answer:
A. When an action causes something to come into effect
Step-by-step explanation:
The concept of cause and effect refers to the relationship between an action and its resulting outcome or effect. When an action causes something to come into effect, it means that the action is the catalyst or trigger that leads to a specific outcome or consequence. For example, if someone turns on a light switch, the action of flipping the switch causes the light to come into effect and illuminate the room. This cause-and-effect relationship is commonly observed in various aspects of life, where actions or events lead to specific outcomes or consequences.
