With which Indian bank did Google initially tie up to launch its mobile payments app Tez?

Introduction / Context:
Google launched its mobile payments app Tez in India to enable simple and secure digital transactions using the Unified Payments Interface platform. Banking partnerships were crucial for this launch. This question tests knowledge of which bank was specifically highlighted in general knowledge sources as Googles tie up partner for Tez.

Given Data / Assumptions:

- The question asks about the bank with which Google tied up for its Tez app. - Four major Indian banks are listed as options. - The context is early launch phase information used in competitive exam general knowledge.

Concept / Approach:
Tez, which was later rebranded as Google Pay, worked with multiple banks via the national digital payments infrastructure. However, at the level of exam oriented current affairs, Tez was often associated with a key partnership with State Bank of India. Many question banks frame it as a direct pair, asking with which bank Google tied up for Tez, and they expect SBI as the answer.

Step-by-Step Solution:
Step 1: Recall that Tez operated through the Unified Payments Interface system and supported accounts at many banks. Step 2: Remember that general knowledge sources and news items often highlighted the association between Tez and SBI, the largest public sector bank in India. Step 3: Note that Axis Bank and HDFC Bank were also early partners, but the most commonly quoted bank in exam material is SBI. Step 4: Punjab National Bank is a large bank but was not the primary name linked in simplified exam questions about Tez. Step 5: Therefore select SBI Bank as the expected answer for this question.

Verification / Alternative check:
When revising current affairs compilations from the period of the Tez launch, candidates can see that many practice questions explicitly mention Google tying up with SBI for Tez, even though the technical implementation relied on multiple banking partners. This consistency across exam material provides a practical verification for choosing SBI in this question.

Why Other Options Are Wrong:
Axis Bank did partner with Tez but is not usually presented as the single answer in this widely circulated question pattern. HDFC Bank is another large private bank that supported UPI but is again not the expected choice in this specific simplified pairing. PNB Bank is not typically highlighted in association with the initial branding of Tez.

Common Pitfalls:
A common confusion arises because technologically Tez worked with many banks. Exam questions, however, often simplify current affairs into one bank app pairing. Students who have studied from multiple sources should focus on the pairing most repeatedly used in question banks, which in this case is Google Tez with SBI. Reading the question carefully as an exam style recall item, rather than as a technical specification, helps pick the intended option.

Final Answer:
In the context of exam oriented current affairs, Google tied up with SBI Bank for its mobile payments app Tez.
