Question

which of the following is an example of the identifier that represents ground number in wiring diagrams?
a) c501a-17
b) gd 233 bk
c) vpw38
d) ye-bu

Explanation:

In wiring diagrams, ground identifiers often use "GD" (or similar abbreviations related to ground) along with a number and sometimes a color code. Option B (GD 233 BK) has "GD" which is associated with ground, while the other options don't have a clear ground - related identifier. Option A seems like a component or connection identifier, Option C is a general identifier without ground indication, and Option D is likely a color - related identifier (YE for yellow, BU for blue) without ground indication.

Answer:

B) GD 233 BK
