To convert the time in New York to Baghdad, we need to take into account the time difference between the two locations. New York is in the Western Hemisphere and Baghdad is in the Eastern Hemisphere, so they are on opposite sides of the Prime Meridian (0° longitude). The time difference between New York and Baghdad is 9 hours, since Baghdad is 9 hours ahead of New York. Therefore, if the deadline in New York was 7 p.m. on 15th January, 1991, it would be 4 a.m. on 16th January, 1991 in Baghdad. To arrive at this answer, we need to add 9 hours to the time in New York to get the time in Baghdad. Thus, the correct answer is option D: 3 a.m. on 16th January.
