Choose the correct translation for the following statement: 'A previsão de demanda, devido à grande quantidade de variáveis que podem influenciá-la na vida prática das empresas, é realizada sempre considerando dados qualitativos (opinião de especialistas, conselhos de categoria, pesquisas de mercado) e quantitativos (crescimento populacional, evolução das vendas, variação dos indicadores econômicos) combinados com os diversos modelos matemáticos para que possamos, dessa maneira, reduzir as incertezas da previsão.'

a) Demand forecasting, due to the large number of variables that can influence it in the practical life of companies, is always carried out considering qualitative data (opinion of specialists, category advice, market research) and quantitative data (population growth, sales evolution, variation of economic indicators) combined with only one mathematical model so that we can reduce the uncertainties of the forecast.
b) Demand forecasting, due to the large number of variables that can influence it in the practical life of companies, is always carried out considering qualitative data (opinion of specialists, category advice, market research) and quantitative data (population growth, sales evolution, variation of economic indicators) combined with various mathematical models so that we can reduce the uncertainties of the forecast.
c) Demand forecasting, due to the small number of variables that can influence it in the practical life of companies, is always carried out considering qualitative data (opinion of specialists, category advice, market research) and quantitative data (population growth, sales evolution, variation of economic indicators) combined with only one mathematical model so that we can reduce the uncertainties of the forecast.
