Even though u consider this logic of four legs, Dogs and Cows are animals that have 4 legs, then also both can come under 4 legs category but remains separated individually.

Right Answer says that the Action and reaction acts simultaneously on different bodies, but I marked my answer as "They act on different objects", the system shows it to be wrong. Please check it..
