各位好，請問一下我想表達下列句子:
所有驗證都在我們的實驗室裡執行，請問用下面哪個句子比較正確?
1. All verifications were performed in our lab.
2. All verifications were performed by our lab.
3. All verifications were completed in our lab.
4. All verifications were completed by our lab.
感謝各位

在你們實驗室不代表就是你們實驗室的人做的，執行的驗證不代表完成了。我推1

1+1

一樓很有說服力

所有驗證都＿1＿我們的實驗室＿2＿1. 完成／執行...對不起打錯1. 在／由2. 完成／執行在我看來，四種組合大同小異。除非是那種講了有法律責任一定要很精確的聲明稿...

1 符合你中文語意。 若 英2語意，翻回中文會是由我們實驗單位負責執行 (人)
