Kudos for correct solution.
What is the units digit of positive integer p?(1) When p is divided by 10, the remainder is 8When a number is divided by 10 we will and if the reminder is 8, we will always get the units digit as 8.
Examples: \(18, 28, 308, 1008\)
As we are getting getting 8 as the units digit for any number divisible by 10, this is SUFFICIENT
Hence, (1) ===== is SUFFICIENT(2) When p is divided by 11, the remainder is 8When we divide a number by 11 and if the number is 8 we can have multiple units digits.
Examples: 19, 30, 63, etc.
As we can see that the units digit is not consistent, we will not be able to answer the question.
Hence, (2) ===== is NOT SUFFICIENTHence, Answer is A _________________
