Concept:Map scale shows the relationship between a distance measured on the map and the corresponding actual distance on the ground.Explanation:The given map is drawn using a representative fraction scale of $1:100,000$.This is read as “one to one hundred thousand”.It means that $1\text{ cm}$ on the map represents $100,000\text{ cm}$ on the ground.Since $1\text{ km}$ is equal to $100,000\text{ cm}$, the ground distance converts directly into kilometres.Therefore, $1\text{ cm}$ on the map represents $1\text{ km}$ on the ground.This corresponds exactly to the scale statement “$1\text{ cm}$ to $1\text{ km}$”.Answer:B. $1\text{ cm}$ to $1\text{ km}$
