Write the following sets in Roster form :
(i) `A={x:x" is an integer" and-3lexle7}`
(ii) B = {x:x is natural number less than 6}
(iii) C = {x : x is a two-digit natural number such that the sum of its digits is 8}
(iv) D= {x : x is a prime number which is divisor of 60}
(v) E = The set of all letters in the word TRIGONOMETRY
(vi) F = The set of all letters in the word BETTER.
