Answer to the quiz: Should You Capitalise Units of Measurement Named After People?
Capitalisation of SI units named after people. The general consensus is that if the unit is named after a person, the symbol is capitalised (first letter only), but the spelled-out word is not capitalised (unless it begins a sentence) because it isn’t a proper noun. Examples include newton (N), pascal (Pa), joule (J), watt (W).
So, B is incorrect.
