Explanation:

At least 44 people were crushed to death in a stampede as tens of thousands of ultra-Orthodox Jews gathered in northern Israel to celebrate the annual Lag B’Omer festival.

• Lag B’Omer is an annual Jewish festival observed during the Hebrew month of Iyar.
• It is celebrated on the 33rd day of the Omer, the 49-day period between Passover and Shavuot.
• Lag B’Omer is the only day during the 49-day period when celebration is permitted. Hence, it is common for Jews to schedule weddings on this day every year. Young boys, who have reached the age of three, are also traditionally brought here for their first hair cut.
• To mark the occasion, tens of thousands of ultra-Orthodox Jewish pilgrims make their way to the base of Mount Meron every year, to pay their respects to Rabbi Shimon Bar Yochai, a second century sage and mystic, who is believed to have died on this day.
• The Rabbi’s tomb is a much revered holy site in Israel.

Hence option 4th is correct.
