Pumps shall furnish not less than 65 percent of the total rated head. Which option represents the correct percentage?

Explanation:
The requirement is about a minimum pump head as a percentage of the total rated head. It states the pump must furnish not less than 65 percent of the total rated head, meaning it must produce at least 65% of what the system is designed to need. So the correct percentage is 65%. Values below that (like 50% or 60%) don’t meet the spec, while a higher percentage (like 70%) would also satisfy the requirement in practice, but the question asks for the minimum threshold, which is 65%.
