A galaxy, sometimes called a stellar universe,_______.

(A) may include billions of stars

(B) billions of stars include

(C) billions of stars may be included

(D) including billions of stars

答案显然是A,但是我做题是选的D,我要问的是sometimes called a stellar universe在句中作什么成分？状语吗？独立主格？

是省略形式的插入语，完整的应该是which is sometimes called a stellar universe,...
