Weight is equal to
- mass * acceleration.
- mass * gravity.
- volume * gravity.
Explanation
Weight is the force of gravity on a body, equal to its mass multiplied by the acceleration due to gravity. Mass times a general acceleration gives any force by Newton's second law, but weight specifically uses gravitational acceleration; volume is irrelevant to the calculation.

Hello.
You are wrong. Weight = mass * gravity. http://www.gcse.com/eb/gtest.htm
Mass * acceleration equals force, so answer A is wrong.
