A resposta correta é a alternativa B) Inserir o multímetro em paralelo com o resistor e medir a queda de tensão através dele. Isso ocorre porque, ao medir a resistência de um resistor, é necessário que ele esteja isolado do circuito, ou seja, não haja corrente fluindo através dele. Ao inserir o multímetro em paralelo com o resistor, a corrente flui através do resistor e do multímetro, permitindo que a queda de tensão seja medida e, a partir disso, a resistência possa ser calculada.
