Answer:

  C)  18

Step-by-step explanation:

  GD = GF + FE + ED

The lengths of GF and ED can be found from the relations ...

  GF + FE = GE

  GF + 1 = 12 . . . .use the given lengths

  GF = 11 . . . . . . . subtract 1

and ...

  FE + ED = FD

  1 + ED = 7 . . . . use the given lengths

  ED = 6 . . . . . . . subtract 1

Then the length of interest is ...

  GD = GF + FE + ED

  GD = 11 + 1 + 6

  GD = 18
