It’s always possible this time of day.

0 M: Sorry I’m late. I tried to call, but my cell phone battery was dead. 02br
00W: What happened? You’re usually so punctual. 02br
00M: The traffic was impossible. There was no way I could’ve avoided it.02br
00W: 01i00____________________02i02br
00(a) It’s always possible this time of day.02br
00(b) You’re early for our meeting.02br
00(c) I happened to be in the neighborhood.02br
00(d) Let me fill you in on what you missed. 02br
02br
00the answer is (d)....but (a) sounds OK to me.. I interpreted the sentence (a) like this way.. " the traffic jam is always bad this time of the day. so being late this time of the day is always possible"02br
02br
00can anyone explain why (a) could not be a possible answer?02br
00thank you. 0-
