Is this a proper LL(1) Grammar?
It's a perfectly valid grammar, and it's certainly LL(1). But since it only generates three sentences, it's probably not what you are looking for.

The three sentences:

a &lt; a
a | a
a / a


For precision: As written, it's not quite correct. In order to achieve what I imagine you meant by the FIRST sets, you'd actually need to he a bit more precise. Instead of using $op$, you write:

$$\begin{align}B&amp; \to \mathbb{&lt;}\\
B&amp;\to\text{|}\\
B&amp;\to\text{/}
\end{align}$$

Alternatively, you could define $op$ as the three possible operators, as above, and leave $B\to op$.

Also: $FOLLOW$ sets (like $FIRST$ sets) are sets of terminals. So $S$ and $C$ are not going to be found in any $FOLLOW$ set. $FOLLOW(B)$ is $\{a\}$.
