Q4 Single choice

Given an HttpServletRequest request and an httpServletResponse response:

43. if (session = = null) {
44. / / do something if session does not exist
45. } else {
46. / / do something if session exists
47. }

To implement the design intent, which statement must be inserted at line 42?

A
session = response.getSession ();
B
session = request.getSession ();
C
session = request.getSession (true);
D
session = request.getSession (false);
E
session = request.getSession ("jsessionid");
