Which pattern match and replace string using regular expressions accomplish this task? (Choose two.)

Answer options

• B. pattern match: ({6}*)
• C. replace string: \[email protected]
• D. pattern match: ({5}\d)
• E. replace string: \[email protected]
• F. replace string: \[email protected]

Correct answer: A, E

Explanation
