Which Indian software services firm completed the acquisition of the London-based digital design and customer experience agency Brilliant Basics?

Introduction / Context:
This question focuses on mergers and acquisitions in the information technology and digital services sector. Indian IT firms have increasingly acquired specialised digital agencies abroad to strengthen their capabilities in user experience, design and innovation. Brilliant Basics is a London based digital design and customer experience agency, and remembering which Indian company bought it helps in questions on corporate current affairs.

Given Data / Assumptions:

• Brilliant Basics is a London based digital design and customer experience firm.
• An Indian software services company completed its acquisition.
• Options are IBM, Google, Microsoft and Infosys.
• The correct answer must match reported corporate news.

Concept / Approach:
Among the options, IBM, Google and Microsoft are global technology giants but not Indian software services companies. Infosys, however, is one of India's leading IT services firms and has been actively acquiring digital agencies to build its digital and design portfolio. The strategy is to identify which option both fits the description of an Indian software services firm and is known to have acquired Brilliant Basics.

Step-by-Step Solution:
Step 1: Immediately eliminate Google and Microsoft as they are multinational product and platform companies, not Indian headquartered software services firms. Step 2: IBM, though it offers services, is a US based company, not Indian. Step 3: Infosys is clearly an Indian IT services company with a global presence. Step 4: News about the acquisition specifically stated that Infosys had completed the acquisition of Brilliant Basics to enhance its digital design and customer experience offerings. Step 5: Therefore, Infosys is the only option that fits all parts of the question.

Verification / Alternative check:
To verify, recall Infosys's strategy in recent years, where it set up and strengthened its design thinking and digital experience capabilities, including through the design studio network. The acquisition of Brilliant Basics was often mentioned together with other digital acquisitions, confirming that Infosys is correctly linked with this London based agency.

Why Other Options Are Wrong:
IBM: A US headquartered technology and consulting company; no major news connects IBM specifically with acquiring Brilliant Basics.
Google: A global internet and technology firm based in the USA, not an Indian software services company and not known for acquiring Brilliant Basics.
Microsoft: Also a US based technology giant, primarily associated with software products and cloud platforms, and not the buyer named in this acquisition.

Common Pitfalls:
One pitfall is to overlook the phrase "Indian software services firm" and simply select a big, familiar tech name such as Google or Microsoft. Another mistake is not tracking corporate acquisitions in the IT services sector, which can cause confusion between companies like Infosys, TCS and Wipro; careful reading of news headlines about each firm helps avoid such errors.

Final Answer:
The London based agency Brilliant Basics was acquired by Infosys.
