Simplify and write the result in standard form, $a+b i$. \[ \frac{-8-10 i}{-2} \] Select one: a. $4+10 i$ b. $4+5 i$ c. $4-5 i$ d. $4-10 i$

Step 1 ：The problem is asking to simplify a complex number division. To solve this, we need to divide both the real and imaginary parts of the numerator by the denominator.

Step 2 ：Given the numerator as (-8-10i) and the denominator as -2.

Step 3 ：Divide both the real and imaginary parts of the numerator by the denominator.

Step 4 ：The result of the division is a complex number with real part 4 and imaginary part 5.

Step 5 ：This matches with option b in the multiple choice answers.

Step 6 ：Final Answer: \(\boxed{4+5 i}\)
