Exports will become ZERORATED under GST, so statements 2 and 3 would have been correct If examiner had used moderate words "GST will help". But he has used 'extreme" words. GST is unlikely to 'drastically' reduce CAD Because of crude oil import and OPEC cartel that manipulates its prices. Similarly, GST is unlikely to enormously increase size of oureconomy (IMF projection ∼1−1.5% addition in growth rate.) and we can't overtake China in near future, because unlike China we are keeping our currency undervalued against dollar. Hence statement 2 and 3 are wrong. We are left with Answer A.
