Adding surfactants in non polar solvent, the micelles structure will look like

(A)(see structure)
✓ Correct
(B)(see structure)
(C)(see structure)
(D)(see structure)

Answer: (A)

Solution

In a non-polar solvent a surfactant assembles into a reverse micelle: the polar head groups turn inward, away from the non-polar medium, while the non-polar hydrocarbon tails point outward into the solvent. The arrangement with the heads clustered at the centre and the tails radiating outward is the reverse micelle formed under these conditions.
