Final answer:
Given that opposite charges attract, and the question suggests an attraction between particles X and Y, it is likely that one has a positive charge and the other a negative charge. The clues from the question point to the idea that X has a positive charge and Y has a negative charge, which would make statement A correct.
The correct answer is A.
Step-by-step explanation:
The question pertains to the comparatives in mass, molar mass, polarity, and charge between two particles, X and Y.
If objects X and Y attract each other and we know that opposite charges attract, it implies that either X has a positive charge and Y has a negative charge or vice versa. If particle Y has a charge and particle X is neutral, they would not attract based on electrostatic principles, as neutrals do not attract charged particles.
Concerning the wave functions and their amplitudes and positions, these facts could inform us about probability densities and positions of particles, which could relate to their polarities. In this context, a larger amplitude near a particular point could mean more electron density and potential for polarity. However, without specific context or information on the nature of X and Y, this alone is not sufficient to make a definitive statement about their relative polarities.
Hence, based on electrostatics alone, if the entities attract each other, we can say that statement A (X has a positive charge and Y has a negative charge) is true because that would be a plausible reason for their attraction.
