Question

multiple-choice question
what do scientific investigations always start with?
a science teacher telling you what to do
a lesson
a question
a fully formed explanation
rewatch
submit

Explanation:

In the scientific method, a scientific investigation begins with a question that arises from observations or curiosities about a phenomenon. A science teacher telling you what to do is not the start of an investigation (it's more of guidance), a lesson is a learning activity not the start of an investigation, and a fully formed explanation is the result of an investigation (like a conclusion), not the start. So the correct option is the one about a question.

Answer:

C. A question (assuming the options are labeled A, B, C, D with C being "A question")
