Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{4 \sqrt{15k}  + 3 \sqrt{5k} }}}}}

Option B is the correct option.

Step-by-step explanation:

\sf{ \sqrt{15k} (4 +  \sqrt{3} )}

Distribute √ 15 k through the parentheses

\dashrightarrow{ \sf{4 \sqrt{15k}  +  \sqrt{15k \times 3}}}

\dashrightarrow{ \sf{4 \sqrt{15k}  +  \sqrt{45k} }}

\dashrightarrow{ \sf{4 \sqrt{15k}  + 3 \sqrt{5k} }}

Hope I helped!

Best regards! :D
