What is the main conclusion of the study described in the text?
a) The mutation in the Sl7-DR2 gene causes an increase in the levels of 7-DHC in tomatoes, which can be converted into vitamin D3 through UVB irradiation, making tomatoes a sustainable source of vitamin D3.
b) The mutation in the Sl7-DR2 gene causes a decrease in the levels of 7-DHC in tomatoes, which can be compensated by the increase in the flow of intermediates from the phytosterol pathway, resulting in higher levels of cholesterol.
c) The mutation in the Sl7-DR2 gene causes a decrease in the levels of tomatine in tomatoes, which can be used to produce supplements of vitamin D3 for vegans.
d) The mutation in the Sl7-DR2 gene causes a decrease in the levels of esculeoside A in mature tomatoes, which can be compensated by the increase in the flow of intermediates from the phytosterol pathway, resulting in higher levels of cholesterol.

A principal conclusão do estudo descrito no texto é que a mutação no gene Sl7-DR2 causa um aumento nos níveis de 7-DHC em tomates, que pode ser convertido em vitamina D3 por meio da irradiação UVB, tornando os tomates uma fonte sustentável de vitamina D3. Portanto, a alternativa correta é a letra A.
