A firm wants to minimize its costs while producing output, q. It utilizes inputs x and y whose prices are w1 and w2 respectively. The firm's production function is q = xy. The optimization problem for the firm can be best represented as:
A) Minimize C = w1x + w2y subject to q = xy
B) Maximize C = w1x + w2y subject to q = xy
C) Minimize C = (w1 + w2)q subject to q = xy
D) Minimize C = w1x^2 + w2y^2 subject to q = xy
