Step 1: Understanding QCBS.
The QCBS (Quality and Cost-Based Selection) method is widely used for consultancy and professional services. Unlike L1 (lowest bid) systems, QCBS balances both quality (technical score) and cost (financial score).
Step 2: Analyze each option.
- (A) Wrong → In QCBS, the technical bid is opened first, not the financial bid. Only technically qualified bidders proceed to financial evaluation. ✗
- (B) Correct → EMD is always submitted along with the bid documents before the opening of technical bids, to ensure seriousness of bidders. ✓
- (C) Wrong → In QCBS, the lowest financial bid is not always awarded. Instead, technical + financial scores are combined. ✗
- (D) Correct → A composite scoring system is used, typically in the ratio 70:30 or 80:20 (technical:financial). ✓
Step 3: Conclusion.
Thus, correct statements are (B) and (D).
Final Answer: \[ \boxed{\text{(B) and (D)}} \]
