Testing support tools are typically used to automate activities that are resource-intensive when done manually, repetitive tasks, and repetitive inspections. However, they are not usually designed to automate activities that cannot be executed manually at all, as such activities may require complex and sophisticated human intervention or decision-making.
Reference: ISTQB CTFL Syllabus, version 4.0, provides an overview of the typical targets of testing support tools, which exclude activities that cannot be executed manually.

The highest level of risk is calculated by considering both the likelihood of failure and the impact value. Risk can be quantified as the product of these two factors:
* A: 20% * £100,000 = £20,000
* B: 10% * £150,000 = £15,000
* C: 1% * £500,000 = £5,000
* D: 2% * £200,000 = £4,000
Therefore, Option A (20% likelihood of failure and £100,000 impact value) represents the highest risk value.
