To determine which element is most likely to replace hydrogen in a displacement reaction, we can look at the reactivity series of metals. The reactivity series arranges metals in the order of their reactivity, with the most reactive being at the top and the least reactive at the bottom.
In displacement reactions, a more reactive element can displace a less reactive element from its compound. So, if we want to replace hydrogen, we need an element that is more reactive than hydrogen.
Looking at the given options, bromine (Br), lithium (Li), oxygen (O), and helium (He), we can eliminate helium and oxygen as options because they are non-metals and cannot easily replace hydrogen.
Next, we can consider lithium (Li), which belongs to the alkali metal group and is known to be highly reactive. It is more likely to replace hydrogen in a displacement reaction.
Therefore, the correct answer is lithium (Li).
