Sector here follows each company's primary business activity, the same classification exchanges and index providers use to build sector indices and decide which companies belong in a sectoral mutual fund's investable universe. A diversified conglomerate can be assigned to the sector that generates most of its revenue even if it has meaningful operations elsewhere, so it's worth checking a company's own segment reporting if its sector tag looks narrower than its actual business.
If you're researching this sector for a thematic or sectoral fund allocation rather than individual stock picking, see sectoral/thematic mutual funds for funds that invest across a sector rather than in a single company.
A sector's weight in a broad index (Nifty 50, Nifty 500) shifts as constituent companies' prices move relative to each other, so this sector's influence on the headline index number isn't fixed - a sector can grow or shrink in index weight over months without any company in it being added or removed. Checking a company's own index membership on its stock page is the real way to see how much index-level moves are attributable to this sector specifically.
