In a lecture hall, students are seated in three parallel rows (Row 1 is north of Row 2, and Row 3 is south of Row 2), each row having 8 seats. All students face north. Twelve students — Allen, Fame, Emma, Alpha, Coco, Nick, Ivory, London, Olive, Unique, Jack, and Den — belong to two classes: Class A (names starting with vowels) and Class B (the rest). Class A students sit in alternate seats starting from the second seat of Row 1 (counting from the left) in dictionary order, followed by Class B students sitting in reverse alphabetical order. This pattern continues in Row 2 and then Row 3, with all students occupying alternate seats only.

Later, these students sit around two circular tables facing the center: Class A at Table 1 and Class B at Table 2. The following conditions apply:

Table 1:

• Allen sits opposite the student who is second from the left end in Row 2.
• The student sitting to the right of Olive in Row 2 sits second to the right of Allen.
• Alpha does not sit adjacent to Olive and sits opposite Emma.

Table 2:

• London sits second to the right of the student adjacent to Unique.
• The student sitting at the extreme end sits third to the left of London.
• Jack sits opposite Den and is not adjacent to Nick.

Question: Who sits fourth to the left of London in the rows-based seating arrangement?
