Exam tip
Understand the requirements for grounding metal conduits in the IRC, including the requirement for grounding at both ends.
Why A is correct
According to Section 250.104(A) of the 2024 IRC, metal conduits must be grounded at both ends. Grounding at one end (Option B) or neither end (Option C) is not compliant. The requirement for grounding in wet locations (Option D) is a separate code section and does not apply to this question.
