\begin{gathered} \text{For making a triangle, } \\ the\text{ sum of two sides must be greater than the third side.} \\ So, \\ A. \\ 3,12,15\Rightarrow12+3=15\Rightarrow it\text{ will not make triangle} \\ B\text{.} \\ 8,12,15\Rightarrow8+12>15\Rightarrow20>15\Rightarrow It\text{ will construct triangle} \\ C\text{.} \\ By\text{ the same condition,it will also not construct triangle.} \\ D. \\ only\text{ last part of it constuct a triangle,which is 8,12,15} \end{gathered}
