The NEMA designation for a 15-ampere, 125-volt grounding-type receptacle is 5-15R. The "5" indicates the configuration of the blades and contacts, and the "15" indicates the maximum amperage rating. The "R" indicates that it is a receptacle (as opposed to a plug, which would be designated with a "P"). The other options are not correct for this specific receptacle.
