A alternativa correta é a letra B) Only statements B and C are true. Isso ocorre porque, de acordo com a descrição do problema, o valor de f(x) é igual a 0,002, que é menor do que 0,03, que é o valor arredondado de 0,0295, que é o resultado da multiplicação de sin(1,5) por cos(1,5). Além disso, a afirmação de que o valor de sin(1,5) é aproximadamente igual a 1 é verdadeira, enquanto a afirmação de que o valor de cos(1,5) é aproximadamente igual a 0,071 também é verdadeira.
