Let $P(h, k)$ with $h \gt 0, k \gt 0$ be a point on the ellipse $\frac{x^2}{a^2}+\frac{y^2}{b^2}=1$, (where $a \gt b \gt 0$ ), whose foci are $F_1$ and $F_2$. The normal at $P$ intersects the major axis at $Q$. If $P F_1: P F_2=2: 1$ then $Q F_1: Q F_2$ equals

  • A
    $3: 2$
  • B
    $1: 2$
  • Correct answer
    C
    $2: 1$
  • D
    $1: 1$
