Which description best matches a residential horizontal sidewall sprinkler?

Explanation:
Residential horizontal sidewall sprinklers are designed to be mounted on a wall with the head projecting into the room, discharging water horizontally. This wall‑mounted, side orientation allows coverage across the room from the side, which is different from ceiling-mounted sprinklers or floor/standpipe mounting. The description that matches this sprinkler is one where the head is on a sidewall, oriented to spray horizontally into the space.
