Answer: C

Explanation:

The provided pseudo code for the Answer program shows a WHILE loop that will always execute because the condition for the loop to terminate (a >= d) is never met within the loop’s body. This results in an infinite loop. Additionally, since the value of ‘b’ is initialized with ‘a + 10’ and ‘a’ starts from a value that is read and then set to 2, ‘b’ will never be equal to 12. Therefore, the ‘THEN’ branch of the IF statement, which includes ‘print(b)’, is unreachable. These are control flow anomalies because they represent logic in the code that will not function as presumably intended.
