Explanation:

ANSWER: (D) 

  • Both Statements 1 and 2 are correct. 

Kilauea Volcano is located the southeastern-most volcano in Hawaii. It overlaps the E flank of the Mauna Loa shield volcano. It Its East Rift Zone (ERZ) has been intermittently active for at least 2,000 years. It is the second-youngest product of the Hawaiian hotspot and the current eruptive center of the Hawaiian–Emperor seamount chain.

  • Statement 3 is correct. 

It is an active shield volcano created as the Pacific tectonic plate moved over the Hawaiian hotspot in the Earth's underlying mantle. The Hawaii Island volcanoes are the most recent evidence of this process that, over 70 million years, has created the 6,000 km (3,700 mi)-long Hawaiian–Emperor seamount chain.

It is one of five subaerial volcanoes that make up the island of Hawaii, created by the Hawaiian hotspot. Kīlauea started as a submarine volcano, gradually building itself up through underwater eruptions of alkali basalt lava before emerging from the sea with a series of explosive eruptions.
