If the sum of square of differences of rank is 50 and number of items ...
Explanation:

Rank correlation coefficient is given by the formula:

r = 1 – (6 Σd²)/(n(n² – 1))

Where,

d = difference between the ranks of corresponding items in the two series

n = number of items

Given,

Σd² = 50

n = 8

Substituting the values in the formula we get:

r = 1 – (6 x 50)/(8(8² – 1))

r = 0.4

Therefore, the rank correlation coefficient is 0.4. Hence, option (B) is correct.
