Since the element Z has a combining power of 3, it can combine with three atoms of a monovalent element, two atoms of a divalent element, or one atom of a trivalent element.

Among the given options, only option A, ZS3, satisfies this requirement as it indicates that Z combines with three atoms of sulfur, which is monovalent.

Option B, ZSO3, suggests that Z combines with one atom of sulfur and three atoms of oxygen, which is not possible given Z's combining power of 3.

Option C, ZS04, suggests that Z combines with one atom of sulfur and four atoms of oxygen, which is not possible given Z's combining power of 3.

Option D, Z03, suggests that Z combines with three atoms of oxygen, which is not possible given Z's combining power of 3.

Option E, Z3Cl2, suggests that Z combines with two atoms of chlorine, which is monovalent, and would require a combining power of 2 for Z, which contradicts the given information that Z has a combining power of 3.

Therefore, the correct formula for the compound of element Z is A. ZS3.
