Which set of transformations would prove ΔQRS ~ ΔUTS?

Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.
Reflect ΔUTS over y = 2, and translate ΔU′T′S′ by the rule (x − 2, y + 0).
Translate ΔUTS by the rule (x + 0, y + 6), and reflect ΔU′T′S′ over y = 6.
Translate ΔUTS by the rule (x − 2, y + 0), and reflect ΔU′T′S′ over y = 2.

Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.

Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.   First Choice.

Step-by-step explanation:

Clearly we need to scale to show similarity of two different sized shapes through transformation.   Only the first choice offers a scaling.  The composed transformations seem to do the right thing, flipping the little triangle up then doubling its size, keeping S fixed.
