Answer: (A)

Variables are factors that can cause something to change or vary. They’re the characteristics, measurements, or quantities that can take on different values across observations or over time. Recognizing variables lets you see how changing one thing might affect another—for example, how occupancy rate can vary with season or how guest satisfaction might change with service quality. In data analysis, you separate independent variables (the ones you change) from dependent variables (the outcomes you measure). In hospitality and tourism contexts, thinking in terms of variables helps explain fluctuations in demand, pricing, or revenue. The other options describe people, a type of ship, or a travel rule, which aren’t terms for factors that change, so they don’t fit.
