In the following passage there are blanks, each of which has been denoted by a letter. For each blank, five options are given. Choose the most appropriate word from the options that fits the blank appropriately.

India's digital payment ecosystem has undergone a __(A)__ transformation in the last decade. The launch of the Unified Payments Interface (UPI) in 2016 proved to be a __(B)__ moment, enabling instant bank-to-bank transfers through simple mobile applications. Within a few years, UPI transactions __(C)__ into billions every month, far __(D)__ the volume of traditional card-based payments. The government's push for financial inclusion, __(E)__ by the Jan Dhan Yojana and the broad penetration of low-cost smartphones, created a __(F)__ environment for digital wallets and payment apps to __(G)__ in smaller cities and rural areas.

Which of the following fit in the given blank (D)?

The correct option is Surpassing.

To determine the most appropriate word for blank (D), let us analyze the context of the sentence:
"Within a few years, UPI transactions __(C)__ into billions every month, far __(D)__ the volume of traditional card-based payments."

The sentence describes the massive growth of UPI transactions, reaching "billions every month," and compares this volume to that of traditional card-based payments. Since UPI has grown dramatically and become the dominant mode of digital transactions in India, its transaction volume has exceeded or gone beyond that of traditional card payments.
Let us evaluate the given options:
1. Matching: Means equal to. While UPI matched card payments at some point, the phrase "far matching" is grammatically incorrect and does not convey the idea of overwhelming growth.
2. Trailing: Means lagging behind. This contradicts the context of UPI's massive transformation and growth into billions of transactions.
3. Duplicating: Means copying or replicating, which does not fit the context of comparing transaction volumes.
4. Surpassing: Means exceeding, rising above, or going beyond. "Far surpassing the volume" perfectly fits the context, indicating that UPI transactions have greatly exceeded traditional card-based payments.
5. Approximating: Means coming close to, which is too weak given the context of UPI's exponential rise and dominance.

Therefore, "Surpassing" is the correct and most appropriate word for blank (D).
