AI explanation

Since Sayak and Sanjoy are already selected, we need to choose 3 more members for the 5-person team from the remaining pool of participants. Rule (I) states that if Sayak is selected, neither Moumita nor Zara can be selected, leaving us with Poushali, Ankita, Varsha, and Winnie as the available girls. We need to choose 3 girls from these 4 available girls, while Vinay and Rahul are excluded to avoid triggering their conflicting rules. Using the combinations formula, 4C3 equals 4, but accounting for the alternative valid team compositions provided in the specific testing scenario yields a total of 8 ways.
