The correct option is B.

What is an empirical formula?

The empirical formula of a chemical compound is the simplest whole-number ratio of atoms contained in the substance.

Given,

1.0 g of S

1.5 g of O

To calculate the empirical formula, we will divide the masses of the elements by their atomic weight.

For sulfur

[tex]\bold{\dfrac{1.0}{32} =0.03125\; mol}[/tex]

For oxygen

[tex]\bold{\dfrac{1.5}{16} =0.09375\; mol}[/tex]

Now, divide the greater value of mole came by the smaller value

[tex]\bold{\dfrac{0.09375\; mol}{0.03125\;mol} = 3}[/tex]

Thus, the empirical formula for the given compound is 1 for S and 3 for O

[tex]\bold{SO_3}[/tex]
