You will be given a definition of a task first, then some input of the task.
You are given a mathematical question described with an open-ended vocabulary. Questions in this task involve real-world situations, describing a mathematical problem. You are also given 4 or 5 answer options (associated with "A", "B", "C", "D", "E"). Do not generate anything else apart from one of the following characters: 'A', 'B, 'C', 'D', 'E'. LaTeX mathematical format (the standard way to express mathematical expressions in the typesetting software known as LaTeX) is used to express equations. Each question is solvable with high school math knowledge. Give only one answer for each question.

The wholesale price of a car is w dollars. The retail price of this car is r percent greater than the wholesale price. During a special promotion, the retail price of the car is then discounted by s percent. Which of the following expressions represents the price, in dollars, of this car during the special promotion?
(A)\(w(
rac { r } { 100 } )(
rac { s } { 100 } )\) (B)\(w(1 +
rac { r } { 100 } )(1 -
rac { s } { 100 } )\) (C)\(w(
rac { rs } { 100 } )\) (D)\(w +
rac { wr } { 100 } -
rac { ws } { 100 } \) (E)\(w(
rac { wr } { 100 } -
rac { ws } { 100 } )\)
Output:
B
