- To solve the series: QUESTION, USINETO, SNTIEO, NIOTE, ?, observe the pattern.

- Each subsequent sequence removes the first letter and reorders the remaining.

- Series steps:

- "QUESTION" loses 'Q', becomes "USINETO".

- "USINETO" loses 'U', becomes "SNTIEO".

- "SNTIEO" loses 'S', becomes "NIOTE".

- "NIOTE" loses 'N', leaving "IOTE".

- Determine next: reorder "IOTE".

- Option:1 ITEO - similar letters but incorrect order.

- Option:2 TEOI - right letters, incorrect order.

- Option:3 ITOE - similar letters, different order.

- Option:4 OEIT - different sequence than required.

- ITOE is the correct answer as it retains the correct set of letters in the next pattern.
