Solution
This question tests possessive pronouns and pronoun-antecedent agreement.
When a city (singular) owns something, use "its" not "their." Think of it like this: "The dog wagged its tail" not "The dog wagged it's tail" or "their tail." The apostrophe in "it's" makes it a contraction meaning "it is" or "it has," while "its" shows ownership.
Option 1 → Wrong contraction; "it's" means "it is," not possession.
Option 2 → "Lias" is gibberish, and word order feels backwards.
Option 3 → "Having" creates an incomplete, dangling construction here.
Option 4 → Perfect! "Its" shows possession, tense works smoothly.
