To solve the multiple choice problem, you need to subtract -3.9 from -1.8.
To do this, you subtract the absolute values and keep the sign of the number with the greater absolute value.
Therefore,
-|-1.8 - 3.9| = |-5.7| = 5.7
Since the original problem is -1.8 - 3.9, the correct answer is -5.7.
So, the correct choice is:
-5.7
