Answer:
D. Following product? differentiation, Goodrick will operate with excess capacity.
Step-by-step explanation:
Due to the fact that there is product differentiation and resulting fresh entries which were attracted by profits in the short-run, in the long run Goodricke will create product by MR and MC equating, as well as the resultant price which will be just as the same to its ATC, thus economic profit will be zero. on the other hand, when the Price (= ATC) > MC, MR = MC, thus ATC curve is falling and not minimized at this point, which will lead to excess capacity.
