Hint: 1. Lakshadweep consists of 3 reefs and 6 underwater sand banks on all 27 islands. There are only 10 islands inhabited.
2. The islands of Lakshadweep are made up of polyps (a small vascular growth on the surface of the mucous membrane) which are the architects and engineers of these atolls (a chain of coral islands).

Complete answer:
The colonies of tiny living creatures found in the oceans are coral reefs. They are the underwater structures of coral polyps shaped by calcium carbonate that are kept together. Coral reefs are also known to be the sea's tropical rainforest and cover only 0.1% of the surface of the ocean, but 25% of marine species are home to them.
Three island types exist in the Arabian Sea.
The Amindivi Islands (consisting of Amini, Keltan, Chetlat, Kadmat, Bitra, and Perumal Par, the six major islands).
The Islands of Laccadive (consisting of five main islands: Androth, Kalpeni, Kavaratti, Pitti, and Suheli Par) and The island of Minicoy.
These islands are currently known collectively as Lakshadweep.
About 200-500 km south-west of the Kerala coast, they are widely distributed.
The northern islands are the Amindivi Islands, while the southernmost is the Minicoy Island.
Both are tiny {Atoll} islands of coral origin and are Surrounded by coral fringes.
Lakshadweep Island, Minicoy Island, with an area of 4.53 sq km, is the largest and most advanced.
Most islands are low in elevation and do not rise above sea level by more than five meters (extremely vulnerable to changes in sea level).
The islands of Lakshadweep are known as coral islands since they were formed from corals. Corals are made from the skeletons, or polyps, of small marine animals.

Hence, Option A. True is the correct answer.

Note: Scattered in the Arabian Sea, the Lakshadweep Islands have located about 225 km to 450 km from the Kerala Coast. The islands covering an area of 32 km2 are made up of 36 small islands, 12 atolls, three reefs and five underwater coasts, with lagoons covering approximately 4200 km2.
The water temperature ranges from 28-31 ° C with salinity varying from 34 percent to 37 percent due to the warm wet climate of these islands.
