Answer by Kaplan:

B.

Income generated from a New Individual Savings Account and a National Savings & Investments Certificate is exempt from Income Tax.

Options A, C & D are incorrect because income generated from shares (dividends) and from NS&I investment account is subject to income tax.

Question to tutor:
So why is (i) included in the answer? Shares in company he works for generates dividends and this is subject to income tax.
