Insufficient information to determine element identity or particle counts Steps:

• Recognize the notation ⁴X, ¹⁴Y, ³⁰Z as likely mass numbers (A) for atoms labeled X, Y, Z, with no atomic numbers (Z) provided.
• Note that element identity depends on Z (number of protons), which is missing.
• Calculate properties like neutrons (A - Z) or compare protons requires Z, which is unknown.
• Conclude no statements can be verified without Z values.

Why A is correct:

• Not enough information; X and Y could be same or different elements since Z_X and Z_Y are unspecified.

Why the others are wrong:

• B: Not enough information; X and Z could share Z or not.
• C: Not enough information; protons equal Z, unknown for X and Y.
• D: Not enough information; neutrons = A - Z, and differing Z makes comparison impossible.

Final answer: Not enough information.
