The statement is true.
In a nonliquidating distribution, when a partnership distributes cash or property to a partner, the partner's basis in their partnership interest is reduced by the amount of the distribution.
In this case, Emma's basis in her partnership interest was $12,000 before the distribution. Since she received $20,000 in cash, her basis is reduced to $0, resulting in an $8,000 gain.
