Answer:
The correct answer would be B, Client Information Sheet.
Explanation:
When a patient is admitted in a hospital and has multiple ailments, like some kidney problem, heart problem, joints problem, blood pressure, sugar, etc, then there would be multiple doctors or the specialists who see the patient. They all will use a common Client information Sheet and put their reviews and suggestions on that sheet so that other doctors also have a look into that before giving medication to the specific patient. This is because all medicines can be just given to the patient without matching with the other medicines. For example there are some medicines of Blood Pressure that cant be given with the medicines of kidneys. So doctors have to give that medicine which matches the rest of the medicines. So when doctors will see the CIS, they will be able to continue the treatment of the patient with ease. So CIS provides continuity when multiple doctors are working on the same patient.

Answer:
Required return is 8.75%
Explanation:
Given,
FV (Face Value) is $1,000
PV (present Value) is computed as:
PV = FV × Price 
= $1,000 × 101.4%
= $1,014
Nper (Number of years) is 8 years
PMT (Monthly payment) is computed as:
PMT = FV × Coupon rate
= $1,000 × 9%
= $90
r (Required return) is computed by using the excel formula:
=Rate(nper, pmt, pv, fv, type)
= Rate (8,90,-1014,1000,0)
= 8.75%
