Explanation:

All statements are correct.

• Wadati – Benioff zone is a zone of subduction, along which earthquakes are common, which are produced by the interaction of a downgoing oceanic crustal plate against a continental plate.

• The Alpide earthquake belt (mid Continental belt) extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. 

• This belt accounts for about 17% of the world’s largest earthquakes.

• Most of the mid-Atlantic Ridge is deep underwater and far from human development.

Hence option 4th is correct.
