(B) The distance $d$ between two parallel lines $ax + by + c_1 = 0$ and $ax + by + c_2 = 0$ is given by the formula $d = \frac{|c_1 - c_2|}{\sqrt{a^2 + b^2}}$.Here,$a = 3$,$b = 4$,$c_1 = 7$,and $c_2 = -5$.Substituting these values into the formula:$d = \frac{|7 - (-5)|}{\sqrt{3^2 + 4^2}}$$d = \frac{|7 + 5|}{\sqrt{9 + 16}}$$d = \frac{12}{\sqrt{25}}$$d = \frac{12}{5}$.
