都可以的
意思说这似乎是没有人知道发生了什么
A是过去式，B是一般现在时， 这里应该用A，因为从句中knew 是过去式。
这时应该选用B, 解释是： 1. It是形式主语, 真正主语是一个句子" nobody (主) knew(谓) what had happen(宾语从句)", 从'knew“可以看出这个句子是一个一般过去时时态,所以整个句子应选用"It seems"，选用一般现在时, 2. 如果问题换成是____ nothing had happened,就应选 B,选用一般过去时 it seemed

这时应该选用B, 解释是： 1. It是形式主语, 真正主语是一个句子" nobody (主) knew(谓) what had happen(宾语从句)", 从'knew“可以看出这个句子是一个一般过去时时态,所以整个句子应选用"It seems"，选用一般现在时, 2. 如果问题换成是____ nothing had happened,就应选 B,选用一般过去时 it seemed
看明白没? 结论就是: 宾语从句中的时态要比整个句子的时态要过去一级, 如: 如宾语从句中选用一般过去时/过去进行时,主句中就选现在时(seems), 如果宾语从句中选用过去完成时,主句中就选一般过去时(seemed)
排序: 过去完成时-->过去进行时/一般过去时-->一般现在时/现在进行时-->一般将来时/将来进行时-->将来完成时
