Concept:For points on the same longitude, the distance is measured along the meridian, where $1^\circ$ of latitude is approximately $111$ km.Explanation:The given latitudes are $8^\circ$N and $10^\circ$S. Because they lie on opposite sides of the Equator, the total angular difference is the sum of their absolute values.Total angular difference $= 8^\circ + 10^\circ = 18^\circ$.Multiply by $111$ km per degree: $18 \times 111 = 1{,}998$ km.Thus the distance between the two places along the same longitude is $1{,}998$ km.Answer:B. 1,998 km
