Firstly, we must evaluate the expression inside the absolute value brackets.

$6.3 + (-4.2) = 2.1$

Taking the absolute value of this gives us:

$|2.1|=2.1$

Adding 3.8 to 2.1 gives us the final answer of:

$3.8+2.1=5.9$

Therefore, the best choice is C.

Evaluate the Expression 3.8+∣6.3+(−4.2)∣3.8 + | 6.3 + ( - 4.2 ) |3.8+∣6.3+(−4.2)∣
