  A. 10. Cookie c = new Cookie("creditCard", usersCard);11. c.setSecure(true);12.
  B. setAge(10368000);13. response.addCookie(c);
  C. 10. Cookie c = new Cookie("creditCard", usersCard);11. c.setHttps(true);12.
  D. setMaxAge(10368000);13. response.setCookie(c);
  E. 10. Cookie c = new Cookie("creditCard", usersCard);11. c.setSecure(true);12.
  F. setMaxAge(10368000);13. response.addCookie(c);
  G. 10. Cookie c = new Cookie("creditCard", usersCard);11. c.setHttps(true);12.
  H. setAge(10368000);13. response.addCookie(c);
  I. 10. Cookie c = new Cookie("creditCard", usersCard);11. c.setSecure(true);12.
  J. setAge(10368000);13. response.setCookie(c);
