Consider $B$ to be the set of positive integers that have no prime factors other than $2$, $3$, $5$, or $7$. The infinite sum
\[
\frac{1}{1} + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} + \frac{1}{5} + \frac{1}{6} + \frac{1}{7} + \frac{1}{8} + \frac{1}{9} + \frac{1}{10} + \frac{1}{12} + \frac{1}{14} + \frac{1}{15} + \frac{1}{16} + \cdots
\]
of the reciprocals of the elements of $B$ can be expressed as $\frac{p}{q}$, where $p$ and $q$ are relatively prime positive integers. What is $p+q$?
A) 38  
B) 42  
C) 43  
D) 51  
E) 56
