Answer:
Not true: B. The radicand has been multiplied by -1.
Explanation:
The parent function of √x has been vertically reflected and translated, but has not been horizontally reflected. Hence the sign of x is positive, not multiplied by -1.
_____
In the attached graph, the parent function (A. y=√x) is shown in purple. The function with the radicand made negative is shown in red (as a dashed line). Clearly this does not match the graph provided with your problem.
The function shown in green has the transformations described by answers C and D.
