Final answer:
The student appears to be asking about Viper's Snakebite ability from the video game Valorant which lasts for 8 seconds, but the provided reference information is about real-world snake venom effects.
Step-by-step explanation:
The question seems to be asking about Viper's Snakebite ability (C) from the video game Valorant. However, the information provided relates to the scientific aspects of actual snakebite venom and its effects on humans, which do not correspond to the abilities of characters in a video game. In Valorant, Viper's Snakebite ability lasts for 8 seconds. It is important to differentiate between the video game's mechanics and real-life snakebite information, as they are not related.
