Consider the following statements and select the correct answer using the codes given below : The ships on the North Atlantic sea route are forced to the South of the true great circle route by :

(1) Fog associated with the contact of the cold Labrador current and the warm Gulf stream current.
(2) Icebergs brought southward by the Labrador current at certain seasons of the year.
(3) The strong polar icy winds from the North.
(4) The projecting landmass of Northeastern North America and the presence of warm Gulf stream current.
Codes :

  • A.(1) and (2) are correct.
  • B.(1), (2) and (3) are correct.
  • C.(1) and (3) are correct.
  • D.All are correct.

Answer: A

The ships on the North Atlantic sea route are forced south of the true great circle route by fog, where the cold Labrador current meets the warm Gulf Stream, and by icebergs brought south by the Labrador current at certain seasons, so (1) and (2) are correct. The strong polar winds and the landmass of north-eastern North America are not the reasons given for the detour. Option A is correct, and the options that add (3) or (4) are wrong.
