Prophase I would be correct...
Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.

Answer:
Letter A - True
Explanation:
Science is in fact limited to topics in which evidence can be gained through experiments and/or observations.
This happens because to realize science, scientists have to strictly follow the scientific method. And in this method, essential steps are observation, formulation of hypothesis and experimentation.
It is also important to note that not all knowledge can be covered by the scientific method, this does not mean that it is not valid, just that it is not science.
