According to the LEED v4 Minimum Program Requirements (MPRs), there is no minimum required number of occupants or full-time equivalents (FTEs) for which a building must be designed to be considered eligible to pursue certification1. However, the project must serve at least one FTE, which is based on an 8-hour day2.
The other options are not part of the MPRs.

An alternative commuting incentive program is a strategy that can be used to encourage alternative transportation methods, such as public transit, carpooling, biking, or walking. An alternative commuting incentive program can provide benefits or rewards for the employees or tenants who use alternative transportation modes, such as subsidies, vouchers, discounts, prizes, recognition, or preferential parking. This strategy can help to achieve LEED Location and Transportation Credit: Alternative Transportation1 . References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide

As per the LEED prerequisite for Environmental Tobacco Smoke (ETS) Control:
"Prohibit smoking in the building and on property within 25 feet from operable windows, entries and air intakes." Building entrances are particularly sensitive areas where smoke can enter the ventilation system.

Covering duct work with plastic is a strategy for improving indoor environmental quality during construction.
Covering duct work with plastic prevents dust, debris, and contaminants from entering the ducts and affecting the air quality of the building. This also reduces the need for cleaning and maintenance of the ducts after construction. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving indoor environmental quality is to "protect ducts during construction by sealing or covering with plastic" [1, p. 16].
