Step 1: The science of fingerprints (dactylography) developed through several workers. Sir William Herschel, an ICS officer, first used fingerprints for identification, and Sir Francis Galton systematized their study. Sir Edward Henry further improved the classification system.
Step 2: The first fingerprint bureau of the world was established in India, at the Writers' Building in Calcutta. This makes India the correct answer.
Step 3: Fingerprints remain the best method of identification of a living or dead person to date because the ridge pattern is unique to each individual and does not change throughout life. Teeth (dental status) are regarded as the second best method of identification.
Step 4: England, China, and Singapore are incorrect as the world's first organized fingerprint bureau was set up on Indian soil.
