Answer:

a. false

b. false

c. false

d. true

Explanation:

(a) False, this is because the set of all real numbers are example of infinite uncountable set.

(b) False, this is because it is undecidable problem to test if a grammar G generates all possible strings over the alphabet and hence to check if set N containing all such CFG is not even recursive-enumerable.

(c) False, this is because there is decidable Turing machine to test if a NFA accepts the input string which includes it's own encoding.

(d) True, this is becsuse it's possible for context-sensative language.
