$\{1,2,3,4,5,6,7,8\}$.

Work Step by Step

$B\cup C$ is the set of all numbers that are either a natural odd number and less than $9$ or a natural even number and less than $9$. Thus $B\cup C$ is the set of all numbers that are a natural number and less than $9$. Thus $B\cup C=\{1,2,3,4,5,6,7,8\}$.
