Explanation:
Migmatite can be defined as metamorphic rock that is formed at high pressure and temperature condition, depicting pro-grade type of metamorphism. This rock is formed from the partial melting of unaltered minerals or those minerals that are slightly modified. But in this process of formation, the bulk mass of the rock remains consistent. It is a transitional rock between the igneous and the metamorphic rock.
Thus, the correct answer is option (C).

Answer:
The correct answer out of the four given options is
option a. light elements with atomic numbers less than 5
Explanation:
Big Bang nucleosynthesis, abbreviated as BBN, also known as primordial nucleosynthesis took place after the Big Bang for about 10 s to 20 minutes and resulted in the yield of isotopes of helium-4 (
), helium-3 (
) which accounts for most of the world's helium, other isotopes of hydrogen in small amounts like deuterium (D or
) and lithium isotope, lithium-7(
) in small amount.
Apart from these stable nuclei, it also yielded two radio-active isotopes: tritium(
) and beryllium-7(
) which due to their unstability later decayed into () and ().
All of these isotopes are of light elements with atomic number less than 5.
