Answer:
(b) Decompression melting , flux melting
Explanation:
Decompression melting : The procedure of decompression melting includes the upward development of the earth mantle to a zone of lower pressure. The decrease in overlying weight empowers the stone to melt, prompting magma arrangement. Magma is shaped by the melting of the earth mantle.
Flux melting :I n molten petrology and volcano logy, flux melting  happens when water and other unstable segments are added to hot strong shake. In designing and metallurgy, transition is a substance, for example, salt, that creates a low dissolving point blend with a metal oxide.
Similarly, the expansion of water and other unstable mixes to rocks made out of silicate minerals brings down the softening temperature of those stones.
