Answer:

C

Step-by-step explanation:

Calculate AB using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 1, - 3) and (x₂, y₂ ) = B(11, - 8), thus

AB = [tex]\sqrt{(11+1)^2+(-8+3)^2}[/tex]

     = [tex]\sqrt{12^2+(-5)^2}[/tex]

     = [tex]\sqrt{144+25}[/tex] = [tex]\sqrt{169}[/tex] = 13 → C
