(1) 14 years before company A began to operate, it was 1912.

(2) \(5\frac{1}{3}\) years after company A began to operate, it was 1931.



(1) 14 years before it began, it was 1912. So when it began the year must have been 1912+14 = 1926. Sufficient.

(2) 16/3 years after it began, it was 1931. 16/3 years means 5 years and 4 months. Here there is no surety. Eg, if company began operation in Dec 1925, then after 16/3 years it would have been April 1931. But if company began operation in January 1926, then after 16/3 years it would have been May 1931. In both these examples, latter year is 1931 only but former years (when the operation began) are different. So cant say. Insufficient.

Hence A answer
