CorrectNot quiteAnswer A
Correct answer: A
Explanation
The seven base units are the metre, kilogram, second, ampere, kelvin, mole and candela.
The newton is derived from them: 1 N = 1 kg m/s².
Worth noting
The candela (luminous intensity) and the mole (amount of substance) sound unfamiliar, which is why students wrongly drop them.
