Then which of the following is trueAPrinciple of mathematical induction can be used to prove the formulaBS(K)⇒S(K+1)S\left( K \right) \Rightarrow S\left( {K + 1} \right)S(K)⇒S(K+1)CS(K)≠S(K+1)S\left( K \right) \ne S\left( {K + 1} \right)S(K)=S(K+1)DS(1)S\left( 1 \right)S(1) is correctCheck answerSkip
