Answer:
A - beta[0]
Explanation:
Beta[0] is the first element of the array, therefore automatically it is a valid element of beta. B and C are disqualified because you would not use single quotations when referring to an element. D is disqualified because the element starts at 0 (beta[0]) and has 50 elements declared, therefore it would end at 49, with beta[49] being the last element.

Answer:
Hydrogen.
Explanation:
Hydrogen is the simplest element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.
Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.
Additionally, all stars are made up of Hydrogen.
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force. Stars are typically made up of two (2) main hot gas, which are Hydrogen (H) and Helium (He).
