Answer:
"Option b and Option d" is the correct option for this question.
Explanation:
In the database, datatype belongs to the information storage medium, which can hold a specific type of value. There are several data types, which is used in database like integer, character, series, floating-point and array numbers, and the rules, that give levels of security to information are known as a security constraints. It may be either developed as rules on integrity, mathematical formalism rules or schematic rules, and other choices were wrong which can be described as follows:
- In option a, The asserts, which is in any exchange in a database, should only modify the information, that is effected in acceptable ways is called consistency, that's why it is wrong.
- In option c, The validity and accuracy of the data in the database can not be ensured, that's why it is wrong.

Answer:
Maintenance Phase
Explanation:
One of the concepts employed in project management for describing stages involved when carrying out an information system development project is the systems development life cycle (SLDC). The cycle which starts from carrying out a feasibility study and ends in maintenance is a highly used conceptual model. There are 5 major stages or phase and they are the; Requirement Phase, Design Phase; Implementation Phase, Test Phase, and the Maintenance phase. The maintenance phase comes when testing has been complete and all enhancement and modifications have already been developed, and the system is operating.
import random
num_rolls = 0
while True:
r1 = random.randint(1, 6)
r2 = random.randint(1, 6)
print("Rolled: " + str(r1) + "," + str(r2))
num_rolls += 1
if r1 == r2 == 1:
break
print("It took you "+str(num_rolls)+" rolls")
I added the working code. You don't appear to be adding to num_rolls at all. I wrote my code in python 3.8. I hope this helps.
