Explanation:

Let’s break it down step by step:

- “Ram goes to school” = "rx gw ts mh"

- “He goes hospital” = "ez gw lp"

- “He studies in school” = "ez yr ga mh"

- “Ram works in hospital” = "rx kt ga lp"

Now, line up what matches.

- “goes” appears in “Ram goes to school” and “He goes hospital” ? codes in common: "gw". So, code for “goes” is "gw"

- “school” in “Ram goes to school” and “He studies in school” ? code in common: "mh"

- “He” in “He goes hospital” and “He studies in school” ? code in common: "ez"

- “in” in “He studies in school” and “Ram works in hospital” ? code in common: "ga"

- That leaves “studies” in “He studies in school,” which hasn’t been matched yet; unused code is “yr”

So, “studies” = yr

Option 1: gw – that’s “goes”

Option 2: ez – that’s “He”

Option 3: yr – this is "studies"

Option 4: rx – “Ram”
