Among the following the least unit for length is

Options

  1. Aparsec
  2. Bnanometer
  3. Cfermi
  4. Dangstrom

Correct answer

C. fermi

Step-by-step solution

1 parsec =3.26 l y 3.08 10¹⁶ ~m ; 1 nano meter =1 10⁻⁹ ~m 1 fermi =1 10⁻¹⁵ ~m and 1 angstrom =1 10⁻¹⁰ ~m Therefore the least unit for length among the given is fermi.
