(A) The even numbers in set $A$ are $\{2, 4, 6, 8, 10\}$.There are $5$ such even numbers.The total number of subsets that can be formed using these $5$ elements is $2^5 = 32$.Since we need non-empty subsets, we exclude the empty set $\emptyset$.Therefore, the number of non-empty subsets is $32 - 1 = 31$.
