Concept:When a map is reduced by half, every map distance becomes half, so the denominator of the scale doubles.Explanation:The original scale of the map is $1:50{,}000$.This means $1$ cm on the original map represents $50{,}000$ cm on the ground.When the map is reduced to half its size, $1$ cm on the new map represents $2$ cm on the original map.Therefore, the new scale becomes $1:2 \times 50{,}000 = 1:100{,}000$.Answer:C. $1:100{,}000$
