Base unit is the fundamental unit of measurement that is not mutually dependent. The seven base units are,
Length - meter
Mass- kilogram
Time - second
Temperature - Kelvin
Current - Ampere
Luminous intensity - Candela
Amount of matter - mole
Derived units are derived from the seven base units. Like the area (square meters) is the square of length (meters), volume is the cube of length.

Answer:
The correct answer is a. chemical bond. See the explanation below, please.
Explanation:
The resulting electrostatic interaction is called ionic bond between ions of opposite charge (one negative and one positive). This allows the attraction between both charges, constituting a chemical compound. Eg the Sodium (Na +) ion combines with the Chlorine (Cl-) ion forming Nacl (sodium chloride, known as table salt).

Answer:
The resonance forms of O3 are attached as an image.
Explanation:
A compound with different contributing structures comes together and forms a resonating or intermediate structure that best describes the properties of that compound.
The given compound is ozone, having the chemical formula
O3 = 6 electrons * 3 = 18 electrons
O → prefers to have a complete their octet
The bonding electrons and lone pair electrons are radical electrons that are present on the oxygen atoms tend to delocalize and results in various resonating forms of O3.
