A virus sample multiplies itself by becoming 16 times itself every hour. But due to anti-agent present in the system, only half of them survive every hour. If we start with \(x\) number of virus and after the 8 hours there are \(2^{40}\) viruses, what is the value of \(x\)?
A. \(2^{16}\)
B. \(2^{18}\)
C. \(2^{21}\)
D. \(2^{23}\)
E. \(2^{25}\)
The OA is A
