Why does generating post-retirement income through an SWP in a conservative hybrid mutual fund create less tax drag than bank Fixed Deposits for a retiree in the 30% tax bracket?

[ A ]Because bank fixed deposits are illegal for senior citizens.
[ B ]Because mutual fund SWPs guarantee zero risk of capital loss.
[ C ]Because 100% of bank FD interest is taxed annually at 30% slab rate (under Section 56), whereas each SWP withdrawal taxes only the net capital gain portion (at 12.5% LTCG or 20% STCG), leaving the principal cost recovery tax-free.[ CORRECT ]
[ D ]Because bank FDs do not pay interest.
Takeaway

The correct answer is C: bank FD interest is taxed at the full 30% slab rate on the entire interest amount every year, whereas an SWP taxes only the gain portion of each withdrawal at concessional capital-gains rates, leaving principal recovery untaxed.

Derivation
An FD credits interest annually and the entire interest is added to taxable income at slab rate, so a 30%-bracket investor loses roughly a third of the gross return every year. An SWP redemption, by contrast, is a partial sale of units: each instalment is split by the fund house into a return-of-principal component (untaxed) and a capital-gain component (taxed at 12.5% LTCG or 20% STCG depending on holding period), so effective tax drag on the same headline yield is far lower. This is the standard case study used to demonstrate why decumulation vehicle choice, not just gross yield, drives post-tax retirement cash flow.
Why the others fail
A — Because bank fixed deposits are illegal for senior citizens.
FDs are entirely legal for senior citizens; the real reason is the tax-treatment gap between slab-taxed interest and capital-gains-taxed SWP withdrawals, not legality.
B — Because mutual fund SWPs guarantee zero risk of capital loss.
SWPs from a hybrid fund carry market risk and are not guaranteed; the correct rationale is the tax-efficiency gap, not a (false) capital-safety claim.
D — Because bank FDs do not pay interest.
FDs do pay interest; the comparison concerns how that interest and SWP gains are taxed differently, not whether FDs pay interest at all.
