The dimensions of magnetic intensity are

• A

  $\left[\begin{array}{llll}{\left[\mathrm{L}^{1}\right.} & \mathrm{M}^{0} & \mathrm{~T}^{1} & \mathrm{I}^{1}\end{array}\right]$
• B

  $\left[\begin{array}{lll}\mathrm{L}^{1} & \mathrm{M}^{0} & \mathrm{~T}^{0} & \mathrm{I}^{-1}\end{array}\right]$
• Correct answer
  C

  $\left[\begin{array}{lll}\mathrm{L}^{-1} & \mathrm{M}^{0} & \mathrm{~T}^{0} & \mathrm{I}^{1}\end{array}\right]$
• D

  $\left[\begin{array}{llll}\mathrm{L}^{2} & \mathrm{M}^{1} & \mathrm{~T}^{0} & \mathrm{I}^{1}\end{array}\right]$

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