Answer:
Correct choice is B
Step-by-step explanation:
Smilar triangles have proportional correcponding sides.
If [tex]\triangle BCD\sim \triangle LMN,[/tex]
then write side BC corresponds to side LM, side CD - to side MN and side BD - to side LN.
Hence,
[tex]\dfrac{BC}{LM}=\dfrac{CD}{MN}=\dfrac{BD}{LN}.[/tex]
