I. a2 - 13a + 42 = 0,
II. b2 - 15b + 56 = 0 to solve both the equations to find the values of a and b?	Choose the correct choice
A) If a > b  B) If a ≥ b  C) If a < b  D) If a ≤ b  E) If a = b or the relationship between a and b cannot be established.
Explanation:   I. a2 - 13a + 42 = 0   =&gt;(a - 6)(a - 7) = 0 =&gt; a = 6, 7   II. b2 - 15b + 56 = 0   =&gt;(b - 7)(b - 8) = 0 =&gt; b = 7, 8   =&gt;a ≤ b   Option If a ≤ b
