Which company has become the title sponsor for all matches of Board of Control for Cricket in India (BCCI)?

The correct answer is Mastercard.

Let's break down the context and details surrounding this sponsorship:
1. BCCI Title Sponsorship: The Board of Control for Cricket in India (BCCI) hosts international matches played by India on home soil, as well as domestic tournaments. The title sponsor gains branding rights for all these matches, including name association (e.g., the sponsor's name precedes the series name).
2. Transition from Paytm to Mastercard: In September 2022, Mastercard acquired the title sponsorship rights for all BCCI international and domestic home matches. This happened after fintech company Paytm, which held the sponsorship rights, requested BCCI to assign their remaining sponsorship rights to Mastercard.
3. Sponsorship Scope: This agreement covered all international matches (both men's and women's) played in India, including series like the Irani Trophy, Duleep Trophy, and Ranji Trophy, as well as junior cricket (Under 19 and Under 23) matches played in India.
