Assume that the characteristic functions for individuals 1,2, and 3 are given by V(1) = $20, V(2) = $16, and V(3) = $10 respectively, and value created by the coalition V(1,2,3) = $60.If the payoff to individual 1 is $30, and that to individuals 2 and 3 is $15 each, which of the following statements is true?

A) The given allocation is within the core.
B) 2 and 3 will withdraw from the coalition.
C) 2 will block the imputation.
