The correct answer is B. Two. BICSI outside plant standards limit a single terminal pedestal to serving 300 ft (91.4m) of building frontage, so a 600 ft building requires a minimum of two pedestals.
Question
What is the MINIMUM number of outside building terminal pedestals required to serve a single story office, or office warehouse structure that has ten 18.3 m x 24 m (60 ft x 80 ft) units and the total building length is 183 m (600 ft)?

Why each option
BICSI outside plant standards limit a single terminal pedestal to serving 300 ft (91.4m) of building frontage, so a 600 ft building requires a minimum of two pedestals.
One pedestal cannot serve a 600 ft building because BICSI standards cap a single pedestal at 300 ft of building frontage.
BICSI OSP standards specify that one terminal pedestal can serve a maximum of 300 ft (91.4m) of building frontage. The total building length of 600 ft (183m) is exactly double that limit, so the minimum number of pedestals needed to cover the entire frontage is two - one for each 300 ft zone. Using fewer would leave portions of the building without adequate service point coverage.
Four pedestals exceeds the minimum - only two 300 ft service zones exist for this 600 ft building.
Six pedestals is excessive and does not correspond to the minimum derived from the building length divided by the 300 ft per pedestal rule.
Ten pedestals would assign one per unit, which is not how pedestal minimums are calculated - coverage is based on building frontage length, not unit count.
