Answer:

(A) Controlled experiments/Experimentation

Step-by-step explanation:

Experimental research involves the manipulation of an independent variable and the measurement of a dependent variable. Random assignment to conditions is normally used to create initial equivalence between the groups, allowing researchers to draw causal conclusions.
