C) about 7

Explanation:

Being precise, the average digit span that George Miller found was 9.3. Unlike the average span for letters, which rounds the 7.3 digit. In his investigation, Miller tried to find empirical data for the short term memory using letters and digits. Later investigation showed that short term memory is around 15 o 30 seconds and is based on the repetition of the data trough an acoustic process named 'rehearsal'.
