Explicação passo a passo:

$\mathsf{log\:2 = 0,3}$

$\mathsf{log\:3 = 0,4}$

$\mathsf{log\:5 = 0,7}$

$\mathsf{log\left(\dfrac{12}{5}\right) = log(3.4) - log\:5}$

$\mathsf{log\left(\dfrac{12}{5}\right) = log\:3 + 2\:log\:2 - log\:5}$

$\mathsf{log\left(\dfrac{12}{5}\right) = 4 + 6 - 0,7}$

$\boxed{\boxed{\mathsf{log\left(\dfrac{12}{5}\right) = 0,3}}}\leftarrow\textsf{letra B}$
