The correct option is B 341
According to the divisibility rule of 11, The difference between the sum of the digits in the odd places and the sum of the digits in the even places should be either 0 or a multiple of 11
777⇒ (7+7)−7=7≠0 nor a multiple of 11
∴ 777 is not divisibe by 11
585⇒ (5+5)−8=2≠0 nor a multiple of 11
∴ 585 is not divisibe by 11
341⇒ (1+3)−4=0
∴ 341 is divisibe by 11
