figure

  1. Option A:

    A−CH3CH2CH2−OH,B−CH3CH2CH2−OH\mathrm{A}-\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2}-\mathrm{OH}, \mathrm{B}-\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2}-\mathrm{OH}

  2. Option B:

    A−CH3CH2CH2−OH,B−CH3CH−CH3\mathrm{A}-\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2}-\mathrm{OH}, \mathrm{B}-\mathrm{CH}_{3} \mathrm{CH}-\mathrm{CH}_{3}

  3. Option C:

    A−CH3−COHH−CH3, B−CH3CH2CH2−OH\mathrm{A}-\mathrm{CH}_{3}-\underset{\mathrm{OH}}{\mathrm{C}} \mathrm{H}-\mathrm{CH}_{3}, \mathrm{~B}-\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2}-\mathrm{OH}

    Correct
  4. Option D:

    A−CH3CH2CH3, B−CH3CH2CH3\mathrm{A}-\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{3}, \mathrm{~B}-\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{3}
