• D. None of these

Answer 1

The correct option is B Temporary Effect, observed in organic compound

Electromeric effect is a temporary effect and observed only in organic compounds with multiple bonds in the presence of an attacking reagent. It is defined as the complete transfer of shared $pi$ electrons of multiple bond to one of the atoms in presence of attacking reagent.

$\therefore$ Correct answer is B.
