The Caspian Sea is the odd one out because it's not actually a sea - it's a landlocked lake (the largest inland body of water in the world). All the others (Arabian Sea, North Sea, Tasman Sea) are true seas connected to the world's oceans. The Caspian Sea is surrounded by five countries and has no outlet to the ocean.

Nuclear force (strong nuclear force) operates only at extremely short ranges within the atomic nucleus, about 1-3 femtometers. In contrast, electrostatic, magnetic, and gravitational forces are all long-range forces that can act over infinite distances, with their strength decreasing according to the inverse square law.

Sound wave is the odd one out because it is a mechanical wave that requires a medium (solid, liquid, or gas) to propagate. In contrast, X-rays, gamma rays, and microwaves are all electromagnetic waves that can travel through vacuum and do not require any medium for propagation.

Graphite is the odd one out because it is the only non-metallic element in pure form among the options. Diamond is a crystalline form of carbon but has a different structure. Mica and asbestos are silicate minerals. However, the key distinction is that graphite is an allotrope of carbon with electrical conductivity, while the others are insulators or have different properties. The most likely classification is that graphite is conductive while the others are not.

New Delhi is the national capital of India, while Bengaluru, Mumbai, and Kolkata are major metropolitan cities but not the capital. The capital status makes it the odd one out.

Newton's birth occurred on January 4, 1643, marking the beginning of his remarkable scientific journey. The date discrepancy between options stems from calendar systems, with his birth recorded under the Julian calendar before the Gregorian reform.

Newton's birth date is 4 January 1643 in the Julian calendar. This corresponds to 25 December 1642 in the Gregorian calendar, but the given answer matches the historical record under the Old Style dating system.

23°C is a commonly recommended air conditioning temperature setting as it balances comfort and energy efficiency for most indoor spaces. This temperature is neither too warm (21-22°C might feel slightly stuffy) nor too cold (24°C is unnecessarily cool and wastes energy). 23°C is widely cited as the optimal AC temperature for comfort.
