1. **State the problem:** We want to find which expressions are equivalent to $$-6n + (-12) + 4n$$.
2. **Simplify the original expression:** Combine like terms.
$$-6n + 4n + (-12) = (-6n + 4n) - 12 = -2n - 12$$
3. **Check expression A:** $$4(n-3) - 6n$$
Distribute:
$$4n - 12 - 6n = (4n - 6n) - 12 = -2n - 12$$
This matches the simplified original expression.
4. **Check expression B:** $$2(2n - 6)$$
Distribute:
$$4n - 12$$
This is not equal to $$-2n - 12$$.
5. **Conclusion:** Expression A is equivalent, expression B is not, so option C (None of the above) is incorrect.
**Final answer:** Only expression A is equivalent to $$-6n + (-12) + 4n$$.
