A. B. C. D.Answer - A.
Below are the requirements for AWS Direct Connect.
· Your network must use single mode fiber with a 1000BASE-LX (1310nm) transceiver for 1 gigabit Ethernet or a 10GBASE-LR (1310nm) transceiver for 10 gigabit Ethernet.
· Auto-negotiation for the port must be disabled.
Port speed and full-duplex mode must be configured manually.
· 802.1Q VLAN encapsulation must be supported across the entire connection, including intermediate devices.
· Your device must support Border Gateway Protocol (BGP) and BGP MD5 authentication.
· (Optional) You can configure Bidirectional Forwarding Detection (BFD) on your network.
Asynchronous BFD is automatically enabled for AWS Direct Connect virtual interfaces, but will not take effect until you configure it on your router.
All other options are invalid because these are all key requirements for AWS Direct Connect.

https://docs.aws.amazon.com/directconnect/latest/UserGuide/dc-ug.pdfSetting up an AWS Direct Connect connection requires certain prerequisites, and all of the options listed in the question are required except one. Let's look at each option in detail:
A. Support for the router for IPSec: IPSec is a protocol used for encrypting traffic over the internet. AWS Direct Connect does not require IPSec encryption, but it is recommended for security purposes. Therefore, support for the router for IPSec is required.
B. Support for the router for BGP: BGP (Border Gateway Protocol) is a routing protocol used for exchanging routing information between different networks. BGP is required for establishing a connection between your on-premises network and the AWS Direct Connect location. Therefore, support for the router for BGP is required.
C. Single mode fiber: AWS Direct Connect uses optical fiber cables to connect to the AWS Direct Connect location. Single mode fiber is preferred because it has a lower signal loss over long distances than multi-mode fiber. Therefore, single mode fiber is required.
D. VLAN encapsulation: VLAN (Virtual Local Area Network) encapsulation is used to separate traffic on a network into different virtual LANs. VLAN encapsulation is required for establishing a connection between your on-premises network and the AWS Direct Connect location. Therefore, VLAN encapsulation is required.
Therefore, the option that is not required for setting up the connection is C. Single mode fiber. Although single mode fiber is preferred, it is not required for setting up an AWS Direct Connect connection. You can also use multi-mode fiber for the connection, but it may result in higher signal loss over long distances.
