If the rotation is clockwise, the configuration is R. If the rotation is counterclockwise, the configuration is S.<\/p>\n<p>In the reaction shown, the reactant has two chiral centers. The configuration of the first chiral center is R, and the configuration of the second chiral center is R. The product also has two chiral centers. The configuration of the first chiral center is R, and the configuration of the second chiral center is R. Therefore, the configurations of the reactant and the product are both R, R.<\/p>\n<p>Here is a more detailed explanation of each option:<\/p>\n<ul>\n<li>Option A: R, R. This is the correct answer.
