So,

In order to find numbers that are in between 3/8 and 6/7, Lucy must make common denominators first.

LCM of 8 and 7: 56

Multiply each fraction by the appropriate form of 1:
\frac{3}{8} *  \frac{7}{7}\ AND \  \frac{6}{7} *  \frac{8}{8}

\frac{21}{56}\ AND\  \frac{48}{56}

We can immediately see that any fraction with a numerator between 21 and 48 and a denominator of 56 will fit into the criteria Lucy needs.

The correct option is B.
