Explanation:

* Context Analysis:
* The test objective should beSMART(Specific, Measurable, Achievable, Relevant, Time-bound)." Happier" is subjective and not measurable.
* Evaluation of Options:
* A. It is unlikely that just a version change will make users happier so this is not achievable:
* Incorrect. Achievability isn't the main issue; measurement is.
* B. It cannot be measured because 'happier' is subjective:
* Correct. The issue lies in the inability to quantify or measure the term "happier."
* C. It does not define a timeframe:
* Incorrect. While timeframe definition is important, the primary flaw here is subjectivity.
* D. It is not aligned with the organization's objectives:
* Incorrect. The test objective could align but still fail due to lack of measurability.
* Syllabus Alignment:
* ISTQB emphasizes creating measurable and actionable test objectives (TM-1.4.1).

Explanation:

In the context of a system with a large GUI front end, the biggest risk to the schedule when implementing formal scripted test cases early in the SDLC is the potential need for test maintenance due to changes in the presentation layer. This is because the GUI is often subject to change, especially in theearly stages of development, as feedback is received and design adjustments are made. These changes can render early test scripts obsolete, requiring updates and maintenance, which can be time-consuming and delay the testing schedule.
