Best answer
Correct answer is (d) The soap micelle is stable due to negative charge on its head

The best I can explain: The soap micelle is stable due to the negative charge on its polar head. In the micelle formation, the water insoluble tails are directed towards the centre, and the water soluble heads are on the surface in contact with water.
