Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{4 √(15k) + 3 √(5k) }}}}}$

Option B is the correct option.

Explanation:

$\sf{ √(15k) (4 + √(3) )}$

Distribute √ 15 k through the parentheses

$\dashrightarrow{ \sf{4 √(15k) + √(15k * 3)}}$

$\dashrightarrow{ \sf{4 √(15k) + √(45k) }}$

$\dashrightarrow{ \sf{4 √(15k) + 3 √(5k) }}$

Hope I helped!

Best regards! :D
