(C) The given sequence is: $A, C, A, B, B, D, B, C, C, E, C, ?$Let us group the sequence into sets of three terms:$(A, C, A), (B, B, D), (B, C, C), (E, C, ?)$Observing the pattern within each group:$1$. First group: $(A, C, A) \rightarrow$ The first term is $A$,the second is $A+2=C$,the third is $A$.$2$. Second group: $(B, B, D) \rightarrow$ The first term is $B$,the second is $B$,the third is $B+2=D$.$3$. Third group: $(B, C, C) \rightarrow$ The first term is $B$,the second is $B+1=C$,the third is $C$.Alternatively,looking at the sequence as a whole:$A \xrightarrow{+2} C \xrightarrow{-2} A \xrightarrow{+1} B \xrightarrow{0} B \xrightarrow{+2} D \xrightarrow{-2} B \xrightarrow{+1} C \xrightarrow{0} C \xrightarrow{+2} E \xrightarrow{-2} C \xrightarrow{+1} ?$The pattern follows a cycle of adding $2$,subtracting $2$,adding $1$,and keeping the same value.Following the last term $C$,we add $1$ to get $D$.Therefore,the missing term is $D$.
