Descriptive investigations are not repeatable because they are based only on observations made at a single point in time. The results may vary at a different time. In addition, descriptive investigations do not contain variables that may indicate cause-and-effect relationships.
Answer: A good scientific question has certain characteristics. It should have some answers (real answers), should be testable (i.e. can be tested by someone through an experiment or measurements), leads to a hypothesis that is falsifiable (means it should generate a hypothesis that can be shown to fail).

we have
Let's Isolate the variable y in each of the cases and then compare with Fiona's equation to determine the solution of the problem
case A)
Multiply by both sides
Divide by both sides
therefore
the case A) is not equal to Fiona's equation
case B)
Multiply by both sides
Divide by both sides
therefore
the case B) is not equal to Fiona's equation
case C)
Multiply by both sides
Divide by both sides
therefore
the case C) is not equal to Fiona's equation
case D)
Multiply by both sides
Divide by both sides
therefore
the case D) is equal to Fiona's equation
