Explanation
Cisco's 300 Series (B) and SFE/SGE Switches (E) are the two models in this lineup that include native IPv6 support, making them suitable for modern dual-stack or IPv6-only network deployments.
The 100 Series (A) is an entry-level line focused on basic SMB needs without IPv6 support. The ESW 500 Series (C) is an older SMB-focused line that predates widespread IPv6 adoption and lacks IPv6 routing/management capabilities. The Catalyst 2960 Series (D) is a common enterprise switch, but in the context of this question (which focuses on the SMB/small business switch lineup), it is not among the supported models listed - making it a deliberate distractor based on name recognition.
Memory tip: Think "3s and SGEs speak Six" - the 300 Series and SFE/SGE both start with letters that can remind you of "6" (3×2=6, or "S" for "Supports six"). These are the small-business switches Cisco positioned with IPv6 readiness in that product generation.
