A passage states two sector rules. Rule 1: 'No two aircraft may be within 5 nm laterally at the same altitude.' Rule 2: 'Aircraft at the same altitude on opposite tracks must be vectored to diverge by 30 degrees.' Two aircraft are at FL310, on reciprocal tracks, 6 nm apart laterally. Are they compliant?

1. Yes, lateral separation of 6 nm exceeds 5 nm
2. No, reciprocal-track aircraft at the same altitude must be vectored to diverge
3. Yes, Rule 2 only applies if they are within 5 nm
4. No, only because of altitude
