If \( m \) and \( n \) are integers greater than zero and if \( m < n \), we define \( m \nabla n \) as the sum of the integers between \( m \) and \( n \), inclusive of \( m \) and \( n \). For example, \( 5 \nabla 8 = 5 + 6 + 7 + 8 = 26 \). What is the value of \( \frac{22 \nabla 26}{4 \nabla 6} \) ?
(a) 4
(b) 6
(c) 8
(d) 10
(e) 12
