The pattern involves multiplying consecutive prime numbers and alternately adding or subtracting the next prime. Starting with primes 5, 7, 11, 13, 17: 5×7-6=29 (using 5 and 7, subtract 6), 7×11-21=56 (using 7 and 11, subtract 21), 11×13-71=72 (using 11 and 13, subtract 71). The pattern continues: 13×17-24=197, and 17×19-90=233. Option B (197) fits this complex alternating pattern.
