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  (^{4}He), helium-3 (^{3}He) which accounts for most of the world's helium, other isotopes of hydrogen in small amounts like deuterium (D or^{2}H) and lithium isotope, lithium-7(^{7}Li) in small amount.

Apart from these stable nuclei, it also yielded two radio-active isotopes: tritium(^{3}H) and beryllium-7(^{7}Be) which due to their unstability later decayed into (^{7}Li) and (^{3}He).

All of these isotopes are of light elements with atomic number less than 5.

A magnetic survey can be used to explore for minerals that cannot be seen because the deposit is hidden underground.

<h3>What is Magnetic Survey?</h3>

Magnetic surveying is one of the methods used in archaeological geophysics.

This involves the measurement of and recording of Spartial variations in the earth's magnetic field.

Magnetic survey is also in search for mineral-bearing ore bodies or even oil-bearing sedimentary structures.
