Statement II: The prefix 'micro' corresponds to a multiple of \( 10^{-9} \) and is represented by the symbol \( \mu \). In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 3
Statement I is correct but Statement II is incorrect.
