By domain, we need to find out values which x can take to get a result.
If any value of x, results in negative inside a root, that wont be part of domain.
Looking at options, we can differentiate a/b/c from d/e and select value -6 and check. As -6 can be a value, we can eliminate options a/b/c and consider d/e.
Among d and e, we notice -3 as a value in option E but not d. Upon using it in equation we can see, -3 is in the domain.
Hence we can elimiate d, and select E as the answer.
