The sides of a triangle have lengths $6.5$, $10$, and $s$, where $s$ is a whole number.  What is the smallest possible value of $s$?

$\text{(A)}\ 3 \qquad \text{(B)}\ 4 \qquad \text{(C)}\ 5 \qquad \text{(D)}\ 6 \qquad \text{(E)}\ 7$
By [Triangle Inequality](https://artofproblemsolving.com/wiki/index.php/Triangle_Inequality), $6.5 + s >10$ and therefore $s>3.5$. The smallest whole number that satisfies this is $\boxed{\text{(B)}\ 4}$.
