1. **State the problem:** Calculate the value of the expression $$-3.14 \times 47 + 18 \times 3.14 - 171 \times 3.14$$.
2. **Rewrite the expression:**
$$-3.14 \times 47 + 18 \times 3.14 - 171 \times 3.14$$
3. **Factor out 3.14:**
$$3.14 \times (-47 + 18 - 171)$$
4. **Simplify inside the parentheses:**
$$-47 + 18 = -29$$
$$-29 - 171 = -200$$
5. **Substitute back:**
$$3.14 \times (-200)$$
6. **Multiply:**
$$3.14 \times (-200) = -628$$
**Final answer:** $$-628$$
This corresponds to option B.
