The answer is (B)
beginning in the 1940s, both the United States and Russia lead the way and successfully testing nuclear weapons
U.S. conducted six atomic tests before Russia developed
their very first atomic bomb (RDS-1) and tested it on the 29th of
August, 1949. Testing these bombs back then for both countries were relatively
infrequent because they did not have very many atomic bombs to spare. The
Trinity was tested on the 16th of July 1945 and yielded around 20 kilotons.
Trinity, which was conducted in New Mexico was tested to give an idea of the
actual size and the after- effects of a nuclear explosion. Operation first
lightning or the RDS-1 also known as Joe 1 in the west was tested on August 29th
1949 and considered this test as the first Soviet nuclear test.
