You have the table T $=($name$,$ ssn$,$ phone number$)$ representing a person. Each name is uniquely identified by ssn$,$ but the same name can have multiple phone numbers. Suppose you break the table into two tables T$1=($name$,$ ssn$)$ and T$2=($name$,$ phone number$).$

a$)$ What are the candidate keys of T$,$ T$1,$ and T$2,$ respectively?

b$)$ Does the decomposition remove redundancy? If so$,$ why?

c$)$ Which problems $($i$.$e$.$ operation anomalies$)$ can appear in table T$?$ Explain your answer.
