What are the best investments under Section 80C for tax saving?

80C gives Rs1.5 lakh deduction. Best options ranked: ELSS (3-yr lock-in, equity returns, highest potential), PPF (EEE, safe, 15-yr), NPS Tier-1 (additional Rs50k under 80CCD(1B)), EPF (salary deduction), SSY for girl child. Avoid LIC endowment and ULIP under 80C — high charges destroy returns.
