Correct option is A
Statement 1: Teachers make friends with only tall people.
Statement 2: Tandon is very tall.
Conclusions:
Conclusion I: Tandon is friends with a teacher.
Conclusion II: Tandon is not friends with a teacher.
Based on the statements:
Teachers only make friends with tall people, and since Tandon is tall, it is possible that Tandon is friends with a teacher. However, the statements do not confirm this friendship directly. Therefore, it is unclear whether Tandon is actually friends with a teacher or not.
Since either Tandon is friends with a teacher or is not, one of the two conclusions must be true.
Thus, (a) Either conclusion I or II follows is the correct answer.
