A Person's Body Generates About 0 $\mu$ Ci of Radioactivity! Determine the Total Radioactivity Emitted by 300

A person's body generates about 0.2 $\mu$ Ci of radioactivity! Determine the total radioactivity emitted by 300 students in a lecture hall. (1 Ci = 3.7 $\times$ 10¹⁰ Bq and 1 Bq = 1 decay/s)

A) 2 $\times$ 10⁶ decays/s
B) 9 $\times$ 10¹⁶ decays/s
C) 70 decays/s
D) 2 $\times$ 10⁷ decays/s
E) 7 $\times$ 10³ decays/s
