When I looked out to sea,there was not a ship

When I looked out to sea,there was not a ship _____ sight.
A./ B.about C.in D.by
不好意思啊，C应该是into,麻烦大家重新回答，
The more detailed,the better!
Thanks

呵呵,应该选C,给你简单说说:
大意:当我往外看海时,一艘船也没看见(视野里/不远处没有一艘船).

这里考固定搭配,in sight表示可见,看得见；在望；不远处,在视野范围内.
A显然不行, B D的搭配都不妥.
-----------------------------------------
如果C是into,还是(更)应选C:
into sight进入视野,映入眼帘;很形象的表达:
there was not a ship into sight没有一艘船映入眼帘.
比之in sight效果更好.
