b) $-16m - 72k + 104$

c) $-16m - 72k - 104$

d) $16m - 72k - 104$

Explanation:

Step1: Distribute -8 to 2m

$\boldsymbol{-8 \times 2m = -16m}$

Step2: Distribute -8 to 9k

$\boldsymbol{-8 \times 9k = -72k}$

Step3: Distribute -8 to -13

$\boldsymbol{-8 \times (-13) = 104}$

Step4: Combine all terms

$\boldsymbol{-16m -72k +104}$

Answer:

B) $-16m -72k + 104$
