Q: Local basis of nbhs of points in metric space generates topology: verification using specific theorem

Zachary Let $E$ be a set. Suppose that for each $x$ there is a non-empty collection $\mathcal{B}_x$ of subsets of $E$ such that (B1) $x\in B, \forall B\in\mathcal{B}_x$ (B2) if $B_1\in\mathcal{B}_x$ and $B_2\in\mathcal{B}_x$, then $\exists B_3\in\mathcal{B}_x$ such that $B_3\subseteq B_1\cap B_2$ (B3) i...
