  • A
    slightly higher than that when the thunderstorm is not there
  • B
    uninfluenced by occurence of thunderstorm
  • C
    which depends on the amount of dust in air
  • Correct answer

The rain water after thunderstorm contains dissolved acid and therefore the $\mathrm{pH}$ is less than rain water without thunderstorm.

Hence, the correct answer is option: 'D'.
