Answer: The correct expression is
$\ln 4.$

Step-by-step explanation: We are given to express the following logarithmic expression as a single natural logarithm.

$E=\ln 32-\ln 8.$

We will be using the following logarithmic property:

$\ln(a)/(b)=\ln a-\ln b.$

We have

$E\\\\=\ln 32-\ln 8\\\\=\ln (32)/(8)\\\\=\ln 4.$

Thus, the required single natural logarithm is
$\ln 4.$
