There are two columns. Match Column I with appropriate match(es) in Column II. In case you think that there is no suitable match for any particular option then you can say, "None of the match" for that particular option. Your decision to choose a match should not be based on, "may be" but should be based on, "must be".

Let a, b, c be the sides of triangle ABC.

There are two columns. Each option on the left column may have one or more than one match on the right column. Answer is accepted as fully correct if all matches are correct.

Your decision to choose a match should not be based on, "may be" but should be based on, "must be". Only relevant match should be considered.
