Select the option in which the words share the same relationship as that shared by the given pair of words. Bag : Leather

Explanation

The relationship between "Bag" and "Leather" is that leather is a material from which a bag is often made. Applying this analogy to the options: 1. Mobile: Network - Mobiles use networks, but the relationship is not one of material composition. 2. Plastic: Polymers - Plastic is made from polymers, similar to how a bag can be made from leather. This option fits the pattern. 3. Water: Drinking - Water is something you drink, but it doesn't represent a material from which something is made. 4. Suitcase: Travel - A suitcase is used for travel, but the relationship is not one of material composition. So, the correct option is 2. Plastic: Polymers.
