The correct answer is A. 1.1.1 C. 1.1.8. The pessimistic constraint operator (~>) with a three-part version like ~> 1.1.0 means 'allow only patch-level changes within the 1.1.x series.' Formally, it is equivalent to >= 1.1.0 and < 1.2.0. Therefore: 1.1.1 (A) - valid, it is within the 1.1.x range; 1.1.8 (C) - valid…

Explanation

The pessimistic constraint operator (~>) with a three-part version like ~> 1.1.0 means 'allow only patch-level changes within the 1.1.x series.' Formally, it is equivalent to >= 1.1.0 and < 1.2.0. Therefore: 1.1.1 (A) - valid, it is within the 1.1.x range; 1.1.8 (C) - valid, also within 1.1.x. 1.2.9 (B) and 1.2.0 (D) both exceed the 1.2.0 upper boundary and are therefore rejected. If the constraint had been ~> 1.1 (only two parts), it would allow up to < 2.0.0.
