Answer
# 1
Explanation:

fread reads 10 records and prints the names successfully. It
will return EOF only when fread tries to read another record
and fails reading EOF (and returning EOF). So it prints the
last record again. After this only the condition feof(fp)
becomes false, hence comes out of the while loop.
