Explanation

Row-oriented (in-row) cooling places cooling units directly within server rows, putting temperature management close to the heat source. This architecture delivers predictable cooling (A) because short, contained airflow paths eliminate the guesswork of routing cold air across a large open space - what goes in and comes out is tightly controlled. No raised floor is required (C) because the units draw and expel air at rack level rather than relying on under-floor plenums, making deployment in existing facilities straightforward. Ease of deployment (B) is the third benefit, as modular in-row units can be added incrementally alongside new racks without redesigning the room's infrastructure.

Reduced sensible heat ratio (D) is incorrect because in-row cooling does not change the ratio of sensible to latent heat - it simply manages sensible heat more efficiently, but the SHR characteristic of the load remains the same. Increased mixing of air streams (E) is the opposite of what row cooling achieves; a core purpose of in-row containment is to separate hot exhaust from cold supply, so mixing is minimized, not increased.

Memory tip: Think of in-row cooling as "targeted precision" - it is close, contained, and modular. Any answer suggesting vague, uncontrolled, or large-scale behavior (mixing, floor-dependent systems, unpredictable paths) is pointing away from in-row cooling's strengths.
