$A$ physical quantity is given by $X = M^a L^b T^c$. The percentage errors in the measurement of $M, L,$ and $T$ are $\alpha, \beta,$ and $\gamma$ respectively. The maximum percentage error in the quantity $X$ is:

  • A
    $a\alpha + b\beta + c\gamma$
  • B
    $a\alpha + b\beta - c\gamma$
  • C
    $\frac{a}{\alpha} + \frac{b}{\beta} + \frac{c}{\gamma}$
  • D
    None of these
