The correct Answer is:
2
Statements `(a), (b)`, and `(c)` are correct.
So total score `= 1 + 2 + 3 = 6`
Statement `(a,b)` are factual.
Statement `(c) : (r_(o+))/(r_(ɵ)) = (0.35)/(0.95) = 0.368`
The radius ratio lies in the range of `0.225 - 0.414`, which corresponds to `TV` and the `CN` of `TV = 4`.
