Nuclei
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Nucleus
Singular of nouns ending in -i (from Latin):
Some nouns that came into English from Latin end in -us in the singular. They change -us to -i in the plural. To find the singular, change -i back to -us. So nuclei → nucleus. A nucleus is the central part of an atom or of a cell.
