What are gulfs?</h3>
- A gulf is a large inlet from the ocean into the continent, usually having a narrower opening than a bay, however, this is not always the case in all geographical places thus named.
- The term gulf was traditionally applied to huge, indented areas of saline water surrounded by a coastline.
- Many gulfs, including the Persian Gulf, Gulf of Mexico, Gulf of Finland, and the Gulf of Aden, are important shipping lanes.
- The United States Gulf Coast, often known as the Gulf South, is the coastline that runs along the southern United States where it meets the Gulf of Mexico.
Therefore, (A) A and B are the two letters that represent gulfs.

Explanation:
(i) 1 Astronomical Unit (A.U.) = 1.496 x 10^8 Km.
Therefore, distance of Voyager I from Earth = 71 AU = 71 x 1.496 x 10^8 = 1.062 x 10^10 Km.
(ii) The nearest star to Earth than sun is the Proxima Centauri in the Alpha Centauri system. The Proxima Centauri is 4.22 light years away from Earth.
As, 1 Light year = 63241.1 AU
The distance of the Proxima Centauri from Earth = 4.22 x 63241.1 AU = 266877.3 AU
The distance of the Voyager I from Earth = 71 AU
The number of times the distance of the Proxima Centauri from Earth is greater than that of Voyager I is = 266877.3 / 71
= 3758.835 times.
(iii) Speed of light is 1.079 x 10^9 Km/hr
Light travels 1.079 x 10^9 km in 1 hr
Therefore, 1. 062 x 10^10 Km is traveled by light in = (1.062 x 10^10) / (1.079 x 10^9) hr = 9.84 hours
That means when Voyager I was 71 AU from Earth, a observational data from Voyager I at the speed of light took 9.84 hours to reach Earth.
