Hi so I have a question for math.. the math problem is: The coordinates of the vertices of a quadrilateral are P(1,2), R (1,4), S (3,4), and T (4,2). Quadrilateral PRST is reflected across the y axis to create quadrilateral P'R'S'T'. Which rule describes this transformation?

A. (x, y)- (x,-y)
B. (x, y)- (-x, y)
C. (x, y)- (y,-x)
D.(x, y)- (-y, x)

I think it's c but just want to be sure. thanks

ps the - are supposed to be arrows I can't find anything better to be arrows sorry and negatives sorry if this is confusing! ​
