• B25 to 40 percent
• C45 percent
• D50 percent

Explanation

Integrating a Building Automation System (BAS) onto an existing Local Area Network (LAN) leverages shared network infrastructure, eliminating the need for dedicated proprietary cabling runs whenever devices are added, moved, or changed - industry studies and BAS standards consistently cite 25 to 40 percent as the typical cabling-related cost savings from this approach.

Why the distractors are wrong:

• A (10–20%) understates the savings; that range is more representative of minor optimization tweaks, not full LAN integration.
• C (45%) and D (50%) overstate the benefit - savings that high would require nearly complete elimination of cabling costs, which isn't realistic since some dedicated wiring (sensors, actuators, field devices) always remains.

Memory tip: Think "quarter to nearly half" - integrating BAS onto a LAN cuts cabling costs by roughly a quarter to two-fifths (25–40%), a meaningful but not total reduction, because you still need field-level wiring even when the backbone is shared.
