Final answer:

Granite and basalt are a pair of intrusive and extrusive rocks that do NOT have the same chemical composition.

Step-by-step explanation:

The pair of intrusive and extrusive rocks that do NOT have the same chemical composition is d) Granite and basalt.

Granite is a coarse-grained, intrusive igneous rock that predominantly consists of quartz, feldspar, and mica. It is rich in silica.

On the other hand, basalt is a fine-grained, extrusive igneous rock that contains minerals like pyroxene and plagioclase feldspar. It has lower silica content compared to granite.
