    Olá! Bom vamos lá!

    O nucleotídeo é constituído de um açúcar, um grupo fosfato e uma base nitrogenada. Nesse caso estamos falando de subunidade então podemos dizer que estamos falando do RNA ou DNA, logo, teremos a desoxirribose como açúcar.

    Depois teremos um grupo fosfato e assim as bases nitrogenadas (Guanina, Timina/Uracila, Citosina, Adenina) Sendo que C combina com G e A combina com T/U, vamos usar a base T quando for DNA, e quando for RNA vamos usar U. Por isso a resposta correta é a letra B!

    Espero ter ajudado em algo!
