A
echoes
💡 Explanation:
Echo is a noun that ends in -o, and like other similar words (potato, tomato, hero, torpedo), it forms its plural by adding -es to become echoes. This pattern follows standard English rules for words ending in consonant + o. Echos would be incorrect because it doesn't follow the -es rule, echos' is possessive (not plural), and echoses is not a valid English word form.
