The correct Spanish equivalent of "It's raining" is:
O Está lloviendo.
In Spanish, the verb "llover" means "to rain." When describing the action of raining in the present tense, we use the verb form "está lloviendo" which translates to "it is raining." The word "llueve" is the present tense form for the pronoun "it" followed by the verb "llover," but for the complete sentence, we use "está lloviendo" where "está" means "it is." So, the most appropriate option in Spanish for "It's raining" is "Está lloviendo."
