C is incorrect. A company does not necessarily raise more funds according to its target capital structure because of the economies of scale in raising new capital and market conditions. These short-run deviations are due to the "lumpiness" of security issuance. The marginal cost of capital may increase, reflecting these deviations. 这个解析啥意思？ The cost of additional funds from various sources rises as higher levels of financing are achieved. 这句话后半句看不懂， 来源不同地筹资成本增加，是随着更高地融资？
