This is a problem involving an arithmetic sequence. The formula for the nth term of an arithmetic sequence is:

\[
a_n = a_1 + (n - 1) \cdot d
\]

Where:
- \( a_n \) is the nth term.
- \( a_1 \) is the first term of the sequence.
- \( d \) is the common difference.
- \( n \) is the term number.

Given:
- The first term \( a_1 = 5 \),
- The common difference \( d = 2 \),
- The goal is to find the 8th term (i.e., \( n = 8 \)).

Now, substitute the values into the formula:

\[
a_8 = 5 + (8 - 1) \cdot 2 = 5 + 7 \cdot 2 = 5 + 14 = 19
\]

Thus, the 8th term of the sequence is **19**, which corresponds to option **A**.
