. . . . . . . . and . . . . . . . . operators use same symbol.

The correct answer is $\boxed{\text{B. Addition, multiplication}}$.

Addition and multiplication are the only two binary operations in mathematics that use the same symbol, the plus sign (+). In addition, the two numbers being added are called addends, and the result is called the sum. In multiplication, the two numbers being multiplied are called factors, and the result is called the product.

The other options are incorrect because they do not use the same symbol. For example, subtraction uses the minus sign (-), and division uses the forward slash (/). Negation is not an operation, but a function that takes a number as input and returns its opposite as output.
