The statement "All the people who speak Spanish are at my party" implies that every individual who speaks Spanish is included among the attendees of the party. This is a definitive assertion indicating that if someone is a Spanish speaker, they are guaranteed to be present at the event.

In terms of logic, the use of "all" indicates a universal quantifier, which encompasses the entirety of Spanish speakers in the context of the party. This means there cannot be any Spanish speakers who are not at the party, which aligns perfectly with the selected answer.

The other options suggest varying degrees of presence or absence of Spanish speakers at the party, which do not align with the certainty provided by the original statement. Thus, the only interpretation that holds true is that all Spanish speakers are confirmed attendees at the party.
