Which of the Below Statements About the Rate of Interest

Which of the below statements about the rate of interest and cost of capital is FALSE?

B) Firms will reject only projects whose gain is not less than their cost of financing.
C) The firm's demand for borrowing is negatively related to the interest rate; if the rate is high, only limited borrowing and investment make sense.
