Which of the following tools can be used for session splicing attacks?

ADMutate is a tool that mutates shellcode to produce polymorphic exploit payloads, used to evade IDS shellcode signatures, not for HTTP session splicing.

APNIC (Asia Pacific Network Information Centre) is a Regional Internet Registry that manages IP address allocation in the Asia-Pacific region and has no offensive security tool function.

Whisker, developed by Rain Forest Puppy, is a CGI scanner specifically designed with built-in IDS evasion methods including session splicing, where an HTTP request is broken across multiple TCP segments so no single packet contains a complete signature match. It also supports other evasion techniques such as URL encoding and null method tricks. Whisker is the canonical tool associated with session splicing attacks in security literature and certification exams.

ARIN (American Registry for Internet Numbers) is a Regional Internet Registry responsible for IP address management in North America and is not a security attack tool.
