losing是一种状态,表示一直丢的状态,而它的项链丢了,只是过去的一个动作,已经完成.missed 和disappeared是项链的主动形式,如果说是 her necklace作主语的话,就可以用了,但现在是she found 作主语,表示他发现她的项链不见了

a 应该是lost
b应该是missing
d应该是disapearing这样才可以

a,losing 是进行式，表示正在丢失，显然从“found”中可以看出不符；
b,missed 是错过的意思；
c,gone 是过去完成式，在发现前就已经丢失了，与题意符合；
d,disapearded 是消失的意思，项链可不会魔法，不可能自己不见了。
