This is open to interpretation. Is it (14^3)*x or 14^(3x)?
If it is (14^3)*x, the answer must be zero because you subtract 12x on both sides. 0 = (14^3 - 12)*x.
If it's 14^(3x), none of these answers is correct.

If the x on the second side is not multiplying the exponent
12*x = 14^3 *x the answer is 0.
If x is in the exponent NONE of the written anwers are solution
because the first side increases linearly while the second side increases exponentially and 0 and 1are not solutions.In this case there is no algebraic way to solve but there are two roots and one is very close to zero(approx0.01)

the equation is of the form:
ax=bx
or
x(a-b)=0
x = 0 or (a-b)=0
a-b (in this case: 12-14^3) is not zero, so x must be zero.

0 , assuming the x on the right is not in the exponent
