Suppose two parties, Alice $($A$)$ and Bob $($B$),$ want to establish a common secret key $($D$-$H key$)$ using the Diffie$-$Hellman key exchange technique. They agree on $17$ as the modulus $($p$)$ and $3$ as the primitive root $($g$).$ Party A selects $5$ as her secret key $($a$),$ and party B chooses $10$ as his secret key $($b$).$ Calculate their Diffie$-$Hellman key.

Select one:

a$.3$

b$.11$

c$.2$

d$.9$
