Match List$‐\mathrm{I}$ (Event) with List$‐\mathrm{II}$ (Order of the time interval for the happening of the event) and select the correct option from the options given below the lists.

	List-I		List-II
$\left(\mathrm{a}\right)$	The rotation period of earth	$\left(\mathrm{i}\right)$	${10}^5 \mathrm{s}$
$\left(\mathrm{b}\right)$	Revolution period of earth	$\left(\mathrm{ii}\right)$	${10}^7 \mathrm{s}$
$\left(\mathrm{c}\right)$	Period of a light wave	$\left(\mathrm{iii}\right)$	${10}^{-15} \mathrm{s}$
$\left(\mathrm{d}\right)$	Period of a sound wave	$\left(\mathrm{iv}\right)$	${10}^{-3} \mathrm{s}$

• Correct answer
  A

  $\left(\mathrm{a}\right)‐\left(\mathrm{i}\right)$, $\left(\mathrm{b}\right)‐\left(\mathrm{ii}\right)$, $\left(\mathrm{c}\right)‐\left(\mathrm{iii}\right)$, $\left(\mathrm{d}\right)‐\left(\mathrm{iv}\right)$
• B

  $\left(\mathrm{a}\right)‐\left(\mathrm{ii}\right)$, $\left(\mathrm{b}\right)‐\left(\mathrm{i}\right)$, $\left(\mathrm{c}\right)‐\left(\mathrm{iii}\right)$, $\left(\mathrm{d}\right)‐\left(\mathrm{iv}\right)$
• C

  $\left(\mathrm{a}\right)‐\left(\mathrm{i}\right)$, $\left(\mathrm{b}\right)‐\left(\mathrm{ii}\right)$, $\left(\mathrm{c}\right)‐\left(\mathrm{iv}\right)$, $\left(\mathrm{d}\right)‐\left(\mathrm{iii}\right)$
• D

  $\left(\mathrm{a}\right)‐\left(\mathrm{ii}\right)$, $\left(\mathrm{b}\right)‐\left(\mathrm{i}\right)$, $\left(\mathrm{c}\right)‐\left(\mathrm{iv}\right)$, $\left(\mathrm{d}\right)‐\left(\mathrm{iii}\right)$

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