16 number question

Assume a firm's production function is given as follows: Q = min {18L, 12K). If K = 8 and L = 6, which of the following is correct? O Q = 108, and capital and labor can be substituted for each other at the rate of 1.5 L for 1.0 K. O Q = 96, and capital and labor can be substituted for each other at the rate of 1.5 L for 1.0 K. O Q = 96, and capital and labor can be substituted for each other at the rate of 1.5 K for 1.0 L. O Q = 96, and capital and labor cannot be substituted for each other
