Final answer:
The correct sequence of transformations to produce R' S' T' from RST is a 90° counterclockwise rotation about the origin followed by a translation 2 units right.
Step-by-step explanation:
The correct sequence of transformations to produce R' S' T' from RST is option B. A 90° counterclockwise rotation about the origin followed by a translation 2 units right. This means that first, the shape RST is rotated counterclockwise by 90° around the origin. Then, the resulting shape is translated 2 units to the right. This sequence of transformations will produce the desired shape R' S' T'.
