The SI unit of charge is [[1]]

Remember the fundamentals of an electric charge and its unit. Determine the fundamental unit of electric charge and the unit of charge named after the scientist based on this description. Give the definition of an electric charge unit based on these units.
Electric charge is the property of stuff that causes it to experience a force when put in an electric field. Ampere-second or Coulomb are the SI units of charge. One coulomb of charge travels through the current carrying conductor when one ampere of electric current runs through it for one second.

$\text{ 1coulomb }=\left(1\text{ amphere }\right)(1\backslash \text{ second })$

To solve this problem, we need to understand the International system of units (SI) Unit, fundamental unit, fundamental amount, derived unit, derived quantity, and electric charge. With this knowledge, we can easily approach our solution.
The international system of units, abbreviated as SI, is a scientific method of representing the size or quantity of significant natural occurrences. The system has seven fundamental units from which further units are generated.
The first is a number that denotes the size of the quantity, while the second is the standard.
The standard used to measure a physical quantity is referred to as the quantity's unit.

Fundamental units are the units that are used to measure fundamental quantities.
Fundamental Quantities: Fundamental quantities are physical quantities that do not rely on any other physical quantities for measurement.
Derived units: Derived units are defined as units that are used to measure derived quantities.
Derived Quantities: Physical quantities that are measured using one or more basic quantities are referred to as derived quantities.

Hence, the correct answer is Coulomb.
