The relationship between the number of decibels and the intensity of sound is given by the formula:

dB = 10 log(I/I0)

where I is the intensity of sound in watts per square centimeter and I0 is the reference intensity of sound, which is 10^-12 watts per square centimeter.

Using this formula, we can calculate the number of decibels for the given intensity of sound:

dB = 10 log(11ebbd4d_3ee3_57a9_8a0a_e9770b712550_TB8202_11 / 10^-12)
   = 10 log(11ebbd4d_3ee3_57a9_8a0a_e7.77_TB8202_11)
   = 10 * 75
   = 750

Therefore, the number of decibels for the given intensity of sound is 75. Among the given choices, the closest answer is C, which is 70 decibels.
