Explanation

Options A, C, and D represent the three universally recognized categories of IPv4-to-IPv6 transition technologies: conversion/translation (e.g., NAT64) allows IPv4 and IPv6 devices to communicate directly by translating packet headers; dual stack runs both protocols simultaneously on the same device or network, enabling gradual migration; and tunneling encapsulates IPv6 packets inside IPv4 packets (e.g., 6to4, Teredo) to carry IPv6 traffic across existing IPv4 infrastructure.

Option B, "forwarding-routing technology," is the distractor - while routing and forwarding are fundamental networking concepts, they describe how packets move within a single protocol, not a mechanism for bridging the gap between IPv4 and IPv6 during transition.

Memory tip: Use the acronym DCT - Dual stack, Conversion, Tunnel - the three pillars of IPv6 transition. Think of them as "speak both languages (dual stack), translate between languages (conversion), or smuggle one language inside the other (tunnel)."
