As we learnt in

Self Inductance -

An emf is induced in the coil or the circuit which oppose the change that causes it. Which is also known back  emf.

- wherein

 

  Three inductors are in parallel

 

\therefore \; \; \frac{1}{L_{(eq)}}= \frac{1}{3}+\frac{1}{3}+\frac{1}{3}= \frac{3}{3}= \frac{1}{1}

\therefore \; \; \frac{1}{L_{(eq)}}=1\: H

\Rightarrow L_{eq.} = 1 H

This option is incorrect

Option 2)

9H

This option is incorrect

Option 3)

0.66 H

This option is incorrect

Option 4)
