The formula to calculate marginal product is: MPn = TPn - TPn-1, where MPn is the marginal product of nth worker and TP is the total product of n workers.

So, the marginal product of the fourth worker would be MP4 = TP4 - TP3

TP3 = Total product of 3 workers = 214
TP4 = Total product of 4 workers = 221

Therefore, MP4 = TP4 - TP3 = 221 - 214 = 7.

Hence, the answer is C) 7.
