For the questions $17=28,$ consider three relations called $R1,R2,$ and $R3.$ The number of tuples in R$1,$ R$2,$ and R$3$ are $10,20,$ and $30$ respectively. The number of attributes of R$1,$ R$2,$ and R$3,$ are $5,10,$ and $5.$ Use the following choices to answer each question.

a$)0$

b$)1$

c$)5$

d$)10$

e$)15$

f$)20$

g$)30$

h$)40$

i$)50$

j$)100$

k$)200$

l$)300$

m$)$ none of the above
