Answer: C) 10

============================================================

Step-by-step explanation:

Reflect point B over line L, and you'll arrive at the red point B' as shown in the diagram below.

Notice that B and B' are the same distance from line L. Both are 1 unit away.

Now reflect B' over line M to get to point B'', which is shown in blue. Both B' and B'' are 4 units away from line M.

All three points B, B' and B'' are on the same vertical line.

Once we plot B'', count the number of spaces from B to B'' and you should count out 10 spaces total.
