What is true of it
B is B, D♯ and F♯ — 1, 3 and 5 counted from B.
On an instrument that cannot reach all 3, the 5 goes first, in that order.
The easiest of the 4 fingerings below is 4322: 4 fingers, held at the 2nd fret.
None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.
Where its notes are on the neck
The brass dots are B, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
