请问这个题目怎么做呀

Valid Java comments include which of the following?
/* this is an /* embedded / comment */
/
this is an // embedded // comment */
// this is a comment */
(a) I only
(b) II and III only
(c) I and III only
(d) I and II only

选择C选项 I是多行注释 III是单行注释

还有一种是/** */ 文本注释

补充一下 题目我好像输入有误

/* this is an /* embedded / comment */
/
this is an // embedded // comment */
// this is a comment */

前一个/为 */

后一个/为 /*
