Answer:
C. log (12) - log (5)
Step-by-step explanation:
You want the expression equivalent to log(12/5).
The relevant rule of logarithms is ...
log(a/b) = log(a) -log(b)
For a=12, b=5, we have ...
log(12/5) = log(12) -log(5) . . . . matches choice C

Additional comment
A logarithm is essentially an exponent. The rules of logarithms match the rules for exponents:
(x^a)/(x^b) = x^(a-b)
