Question on UTXO

Just seeing this now, but I'd say neither answer is correct, but "a" is closer.
UTXO stands for  "Unspent Transaction Output", therefore "b" is definitely incorrect.
Technically, the Inputs for a Bitcoin transaction contain pointers to previous unspent transactions and Outputs contain new unspent transactions.
So "a" is the closest.

Question : WHAT ARE UTXOS IN A BITCOIN BLOCKCHAIN? *

a. These form the inputs and outputs for transactions 

b. Transaction output that has already been expended

Can anyone share their thoughts ?  Thanks
