cause and effect? Causation? reaction? are there any options given?

When one event occurs and another happens as a direct result is called causation.

Causation refers to something that produces an effect. It may also refer to causality, which refers that the cause that produces an effect is responsible for the effect, and in this light, the effect depends on the cause. In other words, causation refers to the relation existing between two different events that may be successive.
