Answer: A

Explanation:

The composting toilet is applicable to the Water Efficiency Credit, Indoor Water Use Reduction for LEED Interior Design and Construction: Commercial Interiors because it significantly reduces the amount of water used for conventional flushing toilets. By composting human waste, this system eliminates the need for water in the disposal process, contributing to indoor water use reduction.

Reference: The LEED v4 Reference Guide for Interior Design and Construction includes the composting toilet as a strategy for reducing water use within the indoor environment1. The LEED v4 Indoor Water Use Reduction Calculator also provides a framework for calculating water savings, where the use of composting toilets can contribute to achieving the prerequisite and credit requirements for water use reduction1.
