Analyze the question prompt

The question asks us to identify which option is NOT a step included in a scientific investigation.

Evaluate option (a)

Forming hypotheses is a fundamental step where scientists propose tentative, testable explanations based on observations.

Evaluate option (b)

Testing hypotheses through controlled experiments or systematic observations is essential to gather empirical evidence.

Evaluate option (c)

Communicating results allows other scientists to review, replicate, and build upon the findings, which is crucial for scientific progress.

Evaluate option (d)

Guessing lacks systematic reasoning, empirical evidence, and testability, making it incompatible with the rigorous scientific method.

Answer:

• a forming hypotheses
• b testing hypotheses
• c communicating results
• d guessing (Correct answer)
