B, C and D are always assumed in order for the experiment to be accurately as possible.
D --> Whether you're in outer space or here, you must get same result which make your experiment universal.
C-->Limiting the parameters involved in the experiment to make it more accurate, similar to ignoring the air friction in an experiment.
B-->Of course it must be done at least twice and must yield same result by same or other person. This involves time proof were we need a perfect incident is needed in order to confirm the observation, just as an eclipse.
I think the answer is A,
It depends upon the experiments factors, example a parameter that involves voltage may not consider it but rather use Charge, wave instead of light. It depends on what a scientist thinks that will make his experiments better. There might be alternatives but they didn't want to because of certain reason.

A is the best answer.
B, C, and D aren't exactly assumed. A conscious effort has to be made to eliminate extraneous variables introduced by the environment. In other words, if your experiment is how much weight per square inch that water will bear before an object sinks, your results in Antarctica would vary drastically from someone else's results in Brazil unless you consciously eliminated the environment as a variable by doing your experiment indoors.

A scientist should not assume that his answer is the only reasonable hypothysis. A

A. If there is no reasonable alternative then the experiment would be complete, and proven true.

A----there is always a alternative to the ending results.

'A' is not necessarily an assumption that is made.
