Options

  1. AII<IV<III<III < IV < III < I
  2. BI<II<IV<IIII < II < IV < III
  3. CII<I<III<IVII < I < III < IV
  4. DI<II<III<IVI < II < III < IV

Correct answer

B. I<II<IV<IIII < II < IV < III

Step-by-step solution

{PK}_{b} ∝ \dfrac{1}{\text{Basic strength}\left({K}_{b}\right)}<br/><br />{K}_{b} ∝ + 1, + Meffect(e−)density)<br/>effect \left({e}^{-}\right) density)<br />{K}_{b} ∝ \dfrac{1}{- L - M\text{effect}}</p><p></p><p>{K}_{b} = 1 > 2 > 4 > 3</p><p></p><p>{PK}_{b} = 1 < 2 < 4 < 3
