Speaker's brave conquests are mentioned or at least cited in the following options from the excerpt:
<em>Option 1</em>, in which he tells about his innumerable combats he had won.
<em>Option 4 </em>also celebrates his fight with Grendel.
In <em>Option 6</em>, the speaker is showing us how valiant his action in the field of war can be.
Therefore, I assume, from my understanding, that these are the three statements from the provided excerpt which focus on the narrators heroic accomplishments.
