105TB
Suggested answer: D

Explanation:

To calculate the required capacity for snapshots after one week for an HPE Alletra 9000, we start by understanding the customer's requirements:

Base volume size: 100TB

Snapshots: 168 snapshots per week

Daily change rate: 15%

The snapshot capacity requirement can be calculated by taking 15% of the base volume size per day, and multiplying it by the number of days (7 days in a week) and the number of snapshots per day.

Daily change: 15% of 100TB = 15TB Total change over a week: 15TB * 7 days = 105TB

Thus, the capacity needed for snapshots after one week is 105TB.
