ROCKS

The correct answer from the following options and given questions is A. Limestone and marble. Both of these rocks are primarily composed of calcite, which is a mineral that reacts with acids by bubbling. This effervescence occurs due to the release of carbon dioxide gas when calcite (CaCO3) reacts with acids like hydrochloric acid.

Granite (option b) is primarily composed of minerals like quartz and feldspar, which do not react with acid.

Sandstone and quartzite (option c) are mainly composed of quartz, which is also resistant to acid.

Slate and conglomerate (option d) are composed of various minerals that do not exhibit the bubbling reaction with acid.
