Analyze the following code.
``` int count = 0; while (count < 100) { // Point A System.out.println("Welcome to Java!"); count++; // Point B } // Point C ``` a. count < 100 is always true at Point A b. count < 100 is always true at Point B c. count < 100 is always false at Point B d. count < 100 is always true at Point C e. count < 100 is always false at Point C
