I am a seed with three letters in my name. Take away the last two and I still sound the same. What am I?

“Nut”

While 'nut' is also a type of seed, it does not have three letters, so it doesn't fit the riddle's criteria.

“Fig”

Although 'fig' is a three-letter word that refers to a fruit, removing the last two letters does not leave a word that sounds the same.

“Pod”

The word 'pod' is related to seeds but is not a seed itself, and it does not meet the three-letter requirement.
