3. The researcher was studying celestial navigation. Celestial means

Answer: B

Explanation:

Celestial means heavenly.

Celestial refers to anything related to the sky or outer space, particularly in a heavenly context. Therefore, the term is correctly associated with the idea of heavenly bodies or phenomena.

A) subterranean.

Subterranean refers to something that exists or occurs under the ground. This option is incorrect as it does not relate to the sky or anything celestial, which is fundamentally associated with outer space.

B) heavenly.

Heavenly is the correct interpretation of celestial, as it pertains to the sky or the universe beyond Earth. This term encompasses stars, planets, and other astronomical entities, aligning perfectly with the context of celestial navigation.

C) oceanic.

Oceanic relates to the ocean; thus, it is not appropriate in the context of celestial navigation. This option fails to capture the essence of what celestial navigation entails, which is focused on celestial bodies rather than bodies of water.

D) coastal.

Coastal pertains to areas near or bordering the sea. Similar to option C, this choice does not connect to the concept of celestial navigation, which is concerned with navigation through the use of celestial bodies, rather than geographical features related to the coast.

Conclusion

The option B, heavenly, accurately encapsulates the meaning of celestial in the context of navigation by the stars and other heavenly bodies. All other options misinterpret or divert from the fundamental definition of celestial, confirming that B is the only appropriate choice in this scenario.
