Answer- A
NATO Secretary-General Jens Stoltenberg will head the NATO for another year, after his contract was extended again.
Mr Stoltenberg’s time as secretary general was due to end in October while his term had already been extended three times. Norwegian-born Mr Stoltenberg was an economist and former Prime Minister and the announcement comes a week before the next NATO summit in Vilnius, Lithuania.
Hence, option 'A' is correct.
