A. Substitution property

The answer above is correct.

The substitution property states that if one variable equals another, the two variables may substitute one another in any equation. The variable "half of all lunch buyers" equals the variable "35% of all students," so the two are interchangeable in the equation involving the percentage of students that purchase pizza.
