Question

if your conclusion does not agree with (disproves) your hypothesis:
your hypothesis is right
your hypothesis is probably wrong
the experiment must be wrong
your observations or data must be wrong

Explanation:

In the scientific method, a hypothesis is a proposed explanation that is tested. If the conclusion (from experiment/analysis) disproves the hypothesis, the most logical inference is that the hypothesis is probably wrong. The other options are incorrect: a disproven hypothesis can't be right; assuming the experiment or data "must" be wrong is too absolute (experiments and data can be valid, and it's the hypothesis that's incorrect).

Answer:

B. your hypothesis is probably wrong
