Agroup of users can perform certain operations on a shared workbook. which option them to update and track changes in the shared workbook?

the
option allows all group members to update information and track changes in the workbook.

the correct answer is moro reflex. this is usually witnessed in infants normally up to the age of 4-5 months (in some cases maybe more)  

it is caused by a sudden loss of support that makes the baby feel as if he or she is falling or is going to fall and hence the flinging of the arms and crying.
