Answer:

Option B. 75

Step-by-step explanation:

we know that

<u>A negative correlation</u> or inverse correlation is a relationship between two variables such that as the value of one variable increases, the other decreases

we know that

For L1=150, K1=7

so

For K2=14, L2=?

we have that

L1*K1=L2*k2

substitute the values

150*7=L2*14

L2=150*7/14

L2=75
