Answer:

B (3 - i)

Explanation:

To find the quotient of the complex numbers you must multiply the numerator and the denominator by the conjugate of the denominator

Example: The conjugate of (3 - i) is (3 + i)


(8-6i)/(3-i) *(3+i)/(3+i)


(3-i)(3+i)=9-i^(2)


i^(2)=-1

So
(3-i)(3+i)=9--1=10

Denominator= 10


(8-6i)(3+i)=24+8i-18i-6i^(2)


24-10i-6i^(2) =24-10i-6(-1)=24-10i+6=30-10i

Numerator = 30 - 10i

Then
(30-10i)/(10) =(30)/(10)-(10i)/(10)  = 3 - i

The correct answer is B
