The possible rational roots are

$=\frac{\text{factors of the constant}}{\text{factors of the lead coefficient}}$

The constant is 14, and its factors are:

$\pm1,\pm2,\pm7,\pm14$

The lead coefficient is 1, and its factors are:

$\pm1$

Then, the possible rational roots for this equation are

$(\pm1,\pm2,\pm7,\pm14)/(\pm1)=\pm1,\pm2,\pm7,\pm14$

Since, 7 is a possible rational root, the answer is option C
