• A. but
• B. atleast
• C. until
• D. however

Answer 1

Answer:

C. until

• but: This word is used to contrast. 
• atleast: This is incorrect usage; "at least" is two words and does not fit the sentence structure.
• until: This means "up to the point in time." / അതുവരെ, ആകുവോളം 
  • Example: "They did not come until the meeting was half over." 
• however: This word means "nevertheless" and indicates a contrast.
