option (b) 9:20 a.m. Sunday

Step-by-step explanation:

Given:

At 11:00 a.m in Riyadh, time at Manila is 4:00 p.m

thus,

the time difference between Riyadh and Manila is 5 hours as 11:00 + 5 hours =  4:00 p.m

thus, Time in Manila is 5 hours ahead of Riyadh

Now,

The plane landed in Manila at 2:00 a.m on Monday

therefore,

the time in Riyadh at which the plane landed in Manila is 2:00 a.m - 5 hours

= 9:00 p.m on Sunday ( or 12 + 9 = 21 hours )

also,

The time taken by plane to reach was 11 hours 40 minutes

i.e the plane left 11 hours 40 minutes before 9:00 p.m on Sunday from Riyadh

Thus,

the time at which plane left from Riyadh = 9 p.m - ( 11 hours 40 minutes )

= 9:20 a.m on Sunday

Hence,

the correct answer is option (b) 9:20 a.m. Sunday
