The following coding system shows the letter codes for numbers. Excluding the exceptions mentioned below, the digits in the question are to be transformed into letter codes as follows:Digit0123456789LetterCodeABCDEFGHIJExceptions:i. If a number begins with a nonzero even digit, that digit should be coded as N.ii. If a number begins with a nonzero odd digit, that digit should be coded as P.iii. If a number begins and also ends with non-zero even digits, those two digits at the extreme ends should be coded as Q.iv. If a number begins and also ends with nonzero odd digits, those two digits at the extreme ends should be coded as W.v. If a number's middle digit is a multiple of 2 that digit should be coded as Z.Barring these exceptions, the other digits should be codified as per the above-mentioned letter codes.Find the appropriate code for the following number-group 3214067

• A. WCBZGAW
• B. WCBZAGW
