Answer 1

Answer : (c) Markovnikov’s rule

Explanation :

In RX and double bonded hydrocarbons kind of reactions. Markovnikov's rule says that, the negative part of the unsymmetrical reagent adds to less hydrogenated (more substituted) carbon atom of the double bond. So here the negative part of the addendum gets attach to that carbon which possess lesser number of hydrogen atoms.
