Explanation:

From 2.00 am Friday to 6.30 pm Saturday we have
24 hours (till 2 am Saturday) + 12 hours (till 2 pm Saturday) + 4.5 hours = 40.5 hours
20 seconds in 3 hours
∴ ? seconds in 40.5 hours
∴ ? = 270 seconds = 4.5 minutes
Time shown = 6.30 pm + 4.5 minutes = 6 hours 34 minutes 30 seconds = 6.34.30 pm

Hence, option 4 is the correct answer.
