Why This Is the Correct Answer
Supported scaffold platforms and walkways are generally at least 18 in. wide unless a listed exception applies. Other choices are special-case or nonmatching widths.
Why the Other Options Are Wrong
Option B: 12 in.
In general project requirements, 12 in. is the wrong selection for Scaffold platform width: 12 in. is not the scaffold dimension or capacity required by the cited OSHA scaffold rule.
Option C: 24 in.
The trap in C is 24 in. That selection is wrong because 24 in. is not the scaffold dimension or capacity required by the cited OSHA scaffold rule.
Option D: 30 in.
Choice D gives 30 in. Its specific error: 30 in. is not the scaffold dimension or capacity required by the cited OSHA scaffold rule.
Memory Technique
Link scaffold platform width to its book condition; a different condition means a different answer than 18 in.
Reference Hint
Open 29 CFR 1926 OSHA Construction Standards; use 29 CFR 1926.451(b)(2) to confirm that Supported scaffold platforms and walkways are generally at least 18 in.
