Final answer:
The antiderivative of a function can be calculated using Integration rules.
Step-by-step explanation:
The antiderivative of a function can be calculated using Integration rules (Option A). Integration rules allow us to find the antiderivative or indefinite integral of a function. These rules include the power rule, constant rule, sum rule, and many others. By applying these rules step by step, we can find the antiderivative of a given function.
