If the perpendicular distances from the points $(2,3),(4, a)$ and $(\alpha, \beta)$ on to the line $3 x+4 y-3=0$ are equal and $4 \alpha-3 \beta+1=0$ then sum of all possible values of $a, \alpha$ and $\beta$ is

• Correct answer
  A

  $\frac{-79}{10}$
• B

  $\frac{83}{15}$
• C

  $\frac{-73}{5}$
• D

  $\frac{28}{15}$

Hence, the correct answer is option: 'A'.
