F1 Visa - Intended Length Of Stay-DS-160

While I am filling DS-160 I am stuck with a question. my I-20 shows the program start date as June 2021 and the end date as Dec 2021. In the DS-160 there i is a question “Intended length of stay in the USA”, should I enter 7 months or I20 duration + OPT duration?

Please answer the query.

You should answer as per I 20
