Vitamin question?
Answers: The B complex vitamens were originally though to be one vitamen and name Vitamen B. Later research showed there be multiplr vitamans in the comples so they be given numbers to differentiate. Still more research showed that some of the vitamins had be duplicated and this explains the missing gaps within numbers.
I have given you a association about b vitamins

Because historically, the B vitamins be once thought to be a single vitamin, referred to as Vitamin B (much like how those refer to Vitamin C or Vitamin D).
Later research showed that they are chemically distinct vitamins that often coexist surrounded by the same foods. So instead of unmarked letters they made these adjectives B vitamins with subscript numbers to identify them. All 8 are required to good robustness, and supplements containing all eight B vitamins are across the world referred to as a vitamin B complex.
