Answer:
In numerical order left to right, they are arranged by the number of protons in the nucleus of a single atom of each element
The correct options are option B and D, that is, wind power and geothermal energy.
The form of energy which is gathered from renewable resources is known as renewable energy. This form of energy gets restocked on a human timescale like wind, sunlight, tides, waves, rain, and geothermal heat.
Renewable energy usually provides energy in four essential fields, that is, air and water heating/cooling, electricity generation, rural energy services, and transportation.

Ionic bond is formed between positive and negative ions.
Positive ion is known as cation (electropositive metal)
Negative ion is known as anion ( electronegative non-metal)
The bond formed between a metal (positive ion) and non-metal (negative ions) is known as Ionic bond.
Ionic form is formed when one or more electrons from the valence shell of an atom (electropositive metal ) are completely transferred to the valence shell of another atom (electronegative non-metal). Ionic bonding is the complete transfer of valence electron(s) between oppositely charged atoms.
For example: Bond between NaCl(sodium chloride) is an ionic bond in which Na (sodium ) is positive ion(metal) which have +1 charge and Cl (chlorine) is negative ion(non-metal) which have -1 charge and the bond formed between Na+ and Cl- is ionic bond.
