1. **State the problem:** We want to find which expressions are equivalent to $$4(3j+(-4))-9$$.
2. **Start by simplifying the original expression:**
$$4(3j + (-4)) - 9 = 4(3j - 4) - 9$$
3. **Distribute the 4:**
$$= 4 \times 3j - 4 \times 4 - 9 = 12j - 16 - 9$$
4. **Combine like terms:**
$$12j - 16 - 9 = 12j - 25$$
5. **Check option A:**
$$-12j - 13$$
This is not equal to $$12j - 25$$, so option A is not equivalent.
6. **Check option B:**
$$-4(-3j + 4) - 9$$
Distribute the -4:
$$= -4 \times -3j + (-4) \times 4 - 9 = 12j - 16 - 9$$
Combine like terms:
$$= 12j - 25$$
This matches the simplified original expression.
7. **Option C:** "None of the above" is false because option B is equivalent.
**Final answer:** Only option B is equivalent to the original expression.
