Let's evaluate the expression carefully:

Given expression:

$3 - 1 + 5 - 1 + 3 - 1 - 5 - 1$

Now, let's simplify it step by step:

1. Start by performing the operations from left to right:

   $3 - 1 = 2$

   $2 + 5 = 7$

   $7 - 1 = 6$

   $6 + 3 = 9$

   $9 - 1 = 8$

   $8 - 5 = 3$

   $3 - 1 = 2$

So, the value of the expression is 2.

Therefore, the correct answer is b. 2.
