Verified Answer :

Answer: Option B experiments

Explanation:

  • Causality is also known as causation or cause and effect. It is defined as the relationship that exists between cause and effect.
  • Among types of research the experiments produce an outcome and have a cause and effect and thus can establish causality.
  • As compared to experiments , the biased studies as the name suggests are biased in nature and thus cannot establish a causality.
