Which of the following statements is true about a 1-L buffer solution prepared by mixing 1.13 mol propionic acid (C2H5COOH) and 2.03 mol sodium propionate (C2H5COONa)? Ka(C2H5COOH) = 1.34 x 10-5? (Choose one option only). Options:

Options:
a. The pH of the above buffer solution is less than the pKa of C2H5COOH.
b. By adding water to dilute the above buffer solution, the pH of the buffer solution will decrease.
c. By adding water to dilute the above buffer solution, the pH of the buffer solution will increase.
d. By readjusting the amount of propionic acid and sodium propionate, we can prepare a buffer solution at pH = 8.00.
e. The pH of the above buffer solution is greater than the pKa of C2H5COOH.
