Option A : Suppose P committed crime. In that case
P says “Q committed the crime.” {incorrect as P committed crime}
Q says “S committed the crime.” {incorrect as P committed crime} -------line1
R says “ I did not do it.” { correct as P committed crime}
S says “What Q said about me is false”. {we already seen at line1 that whatever Q said is incorrect, hence this statement is correct}
Hence as can be seen there are two correct statement. Hence A is not correct option.
Option B : Suppose R committed crime. In that case
P says “Q committed the crime.” {incorrect as R committed crime.}
Q says “S committed the crime.”{incorrect as R committed crime.} ---------line2
R says “ I did not do it.” {incorrect as R committed crime.}
S says “What Q said about me is false”. {we already seen at line2 that whatever Q said is incorrect, hence this statement is correct }
Hence as can be seen there is only correct statement. Hence B is not correct option.
Option C : Suppose S committed crime. In that case
P says “Q committed the crime.”{ incorrect as S committed crime}
Q says “S committed the crime.” {correct as S committed crime} ------line3
R says “ I did not do it.” {correct as S committed crime}
S says “What Q said about me is false”. {as can be seen on line3 whatever Q said is actually true, hence this statement is false/incorrect}
Hence as can be seen there are two correct statement. Hence C is not correct option.
Option C : Suppose Q committed crime. In that case
P says “Q committed the crime.” {correct as Q committed crime}
Q says “S committed the crime.” {incorrect as Q committed crime} ------line4
R says “ I did not do it.” {correct as Q committed crime}
S says “What Q said about me is false”.{correct as seen at line 4 whatever Q said is incorrect , hence this statement is correct}
Hence as can be seen there are two correct statement. Hence D is not correct option.
