Decide Whether Integration by Parts or Substitution Should Be Used $\int \ln 4 x d x$

Multiple Choice

Decide whether integration by parts or substitution should be used to compute the indefinite integral $\int \ln 4 x d x$ If substitution, indicate the value of u; if by parts, indicate f(x) and g(x) .

A) integration by parts; f(x) = 1, g(x) = ln 4x
B) substitution; u = 4x
C) integration by parts; f(x) = ln 4x, g(x) =1
D) integration by parts; f(x) = ln x, g(x) = 4x
E) none of these
