a.
1.松懈的;放松的
2.随意的;悠闲的
当然用 seem+形容词,选择C是正确的,relax+ed 在这里是形容词.
　注意：1.seem后跟不定式（短语）时,要注意不定式所表示动作发生的时间,以此来确定不定式的时态.
　　2.seem后不定式的否定式习惯上用 don’t 来代替,（放在seem 前）,如：
　　You don’t seem to be quite yourself today ( =You seem not (to be) quite yourself today )
a)I seemed to hear a voice in the distance .
b)Your advice seems to be doing me a favor .
　　c)I seem to have caught a cold .

语法上没有错误但是c更为符合英国人的表达习惯。
若是用A的话通常不用seemed而要用tended
c明显非常地道的嗯~
