Answer:
Actually, in physical cosmology, Big Bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than H-1, the normal, light hydrogen, during the early phases of the universe, shortly after the Big Bang. About first millisecond, the universe had cooled to a few trillion kelvins (1012 K) and quarks finally had the opportunity to bind together into free protons and neutrons. Free neutrons are unstable with a half-life of about ten minutes (614.8 s) and formed in much smaller numbers. The abundance ratio was about seven protons for every neutron. Before one neutron half-life passed nearly every neutron had paired up with a proton, and nearly every one of these pairs had paired up to form helium. By this time the universe had cooled to a few billion kelvins (109 K) and the rate of nucleosynthesis had slowed down significantly.

Answer:
The correct answer is b. an operational definition.
Explanation:
An operational definition constitutes the set of procedures that describe the activities that an observer must carry out to receive sensory impressions, which indicate the existence of a theoretical concept to a greater or lesser degree. In this sense, it tries to clearly indicate how the variables are going to be manipulated or measured and also indicates that to measure a variable, it is necessary to carry out a series of activities or procedures. It is the one that builds or adapts from others, based on the observable characteristics of the phenomenon; indicating the concrete, empirical elements or indicators of the fact to be investigated.
