Here only option b and E donot match the criteria
3 and 12 donot match the criteria because the reciprocal add up to 0.4166 which in not greater than \(\frac{1}{2}\)
and 6 and 8 donot match the criteria because the reciprocal add up to 0.291 which in not greater than \(\frac{1}{2}\) or less than \(\frac{1}{3}\)
