An index ETF is designed to track a specific index—which may represent an asset class, market segment, style, sector, or country—so D is correct. Index ETFs are typically passively managed to replicate the performance of a chosen benchmark (e.g., a broad equity index, a sector index, or an international index). This product design feature is fundamental and widely tested on the SIE.

Choice C is incorrect because ETFs are not priced once daily like open-end mutual funds. ETFs trade on an exchange throughout the day and have intraday market prices. Choice B is incorrect because typical retail investors do not redeem ETF shares for cash directly with the issuer. The creation/redemption process is primarily for authorized participants, who transact in large blocks (creation units), usually exchanging baskets of securities. Retail investors buy and sell ETF shares in the secondary market through brokerage transactions. Choice A is incorrect because while ETFs have an indicative intraday value (often called intraday NAV or iNAV), the ETF’s market price can trade at small premiums or discounts based on supply/demand. It does not necessarily trade exactly at “intraday intrinsic value” at every moment, even though the arbitrage mechanism usually keeps deviations relatively small.

For SIE purposes, remember the core ETF distinctions: intraday trading, typically lower expense than many active mutual funds, an index-tracking objective for index ETFs, and a creation/redemption mechanism that supports price alignment with underlying value.
