Step 1: Idiom for (i).
"Keep your head down" is a standard idiom meaning “stay calm/avoid drawing attention.” \(\Rightarrow \)(i) = down.
Step 2: Verb-particle choice for (ii).
"Head out to bat" is the natural sports collocation when a batter goes to the crease. "Head down" would imply moving downward physically, which is incorrect here. \(\Rightarrow \)(ii) = out.
Step 3: Fixed expression for (iii).
"To have a head for something" means to have a talent/aptitude for it. \(\Rightarrow \)(iii) = for.

The idiom is "a cool head on his shoulders," not "for" his shoulders. \(\Rightarrow \)(iv) = on.
