听力原文： It' s almost 2 weeks since a suicide bomber tried to assassinate the president of Sri Lanka, at an election rally in Colombo. The president was injured in the head and face. 22 other people were blown to pieces, including the bomber herself. It is assumed that she belonged to the Tamil Tigers, the guerrillas who have been fighting for a separate state in the north and east of the island for more than 15 years. With shrapnel still in her skull and eye, Mrs. Kumaratunga went on to win a second term in presidential elections which took place last week. Then she came to London for further medical treatment.
How many people were killed in the bombing altogether？

A. 22
B. 23
C. 24
D. 25
