Suppose a population $A$ has $100$ observations $101, 102, . . ., 200$ and another population $B$ has $100$ observations $151, 152, . . ., 250$. If $V_A$ and $V_B$ represent the variances of the two populations,respectively,then $V_A / V_B$ is:

  • A
    $1$
  • B
    $\frac{9}{4}$
  • C
    $\frac{4}{9}$
  • D
    $\frac{2}{3}$
