Fill in the blank with the most appropriate word.
He thought: "What am I going to do?"

The two ways of relating what a person has said are 1)direct and 2)indirect (reported speech).In direct speech, the original speaker's exact words are repeated. In indirect/reported speech, the exact meaning is expressed but not necessarily using the original speaker's exact words. Pronouns and possessive adjectives usually change from first or second person to the third person except when the speaker is reporting his own words. Sometimes a noun can be inserted to avoid doubt.
When we turn direct questions and exclamations into indirect speech, they are converted to affirmative statement .( ? and ! is not used).
Option B is correct as when we convert the given direct question to indirect speech, the question word what is repeated, present continuous to past continuous tense, and I to he.
The other options are wrong as was he, he is, it, and is he going can't be used.
The correct answer is B) what he was going to do
