Correct Answer - Option 2 : T → P → M → F → D

The correct answer is T → P → M → F → D.

  • The SI unit of length is a metre.
  •  When a larger distance is to be covered, we cannot use the metre.
  • To cover a larger distance we use km(kilometre), hm (hectometre), and da (decametre). These are called the multiples of Metre.
  • When the distance is smaller, we use Dm (decimetre, cm(centimetre) and mm (millimetre). These are called the submultiples of Metre.
