99. What was the problem with some of the e-mails? Select one:
a.
They were incorrectly addressed.
b.
They were e-mailed on the wrong date.
c.
They were missing information.

d.
They were sent multiple times.

the answer is subjective. i personally agree with the first answer for this question.

if one isn't strictly talking about objects then the correct answer would be 'my eyes' since according to this riddle i am asleep and in order to answer/open the door i need to open my eyes first of all.

however, if one is specifically looking for an object, then the first thing i would open would be the door

hope this !
