The human circulatory system is vast, with blood vessels totaling approximately 60,000-100,000 miles in length. The claimed figure of 16,80,000 miles (1.68 million) is significantly exaggerated beyond anatom reality. This appears to be a common myth or misrepresentation.

Human fingernails grow at approximately 0.1 inches (2.5 mm) per month, or about 0.003 inches per day. The stated figure of 0.00007 inches is far below the actual growth rate, making this statement false.

115 pounds equals approximately 52 liters of water. This is far beyond normal human water consumption, which typically ranges from 2-4 liters daily. No one routinely 'takes' 115 pounds of water, making False the correct answer.

The statement is FALSE. Centre of mass and centre of gravity are not always identical. Centre of mass is a geometric property based on mass distribution, while centre of gravity depends on the gravitational field. They coincide only in uniform gravitational fields.

Geostationary orbit is at approximately 35,786 km above Earth's equator. This specific altitude allows a satellite to orbit at the same rate as Earth's rotation, making it appear stationary relative to a point on the ground. The orbital period is 24 hours.

Chinese astronauts are called 'taikonauts'. The term derives from 'taikong' (Chinese for space/cosmos) and was coined to distinguish Chinese space travelers from American astronauts and Soviet/Russian cosmonauts. It's now the internationally recognized term for Chinese space program participants.

Dennis Hwang, a 23-year-old web designer at Google, was responsible for creating the special Google doodles (logo variations) for holidays and celebrations during Google's early years. This began in 1999 and became a Google tradition. The other options are incorrect: Larry Page and Sergey Brin were Google's founders, and GoogleMan is not a real person.
