Glover · Answer 1

C. 10 m

That is the correct answer.

Butchy · Answer 2

For any possible triangle, the sum of any two sides must be greater than the third side. In this case the third side must be less than 12+3=15

So only C (10) and D (9) are less than 15 and are the only possible side lengths given your options.
