The patterns formed by that of the streams, rivers and lakes in a particular drainage basin which are administered by the topography of the land constitute the drainage patterns of an area. There are 7 types of drainage patterns:

• Dendritic drainage pattern: It looks like the branching of a tree, found in the regions with homogenous material.

• Parallel drainage pattern: It forms where there is a slope.

• Trellis Drainage Pattern: Its designs look similar to that of the standard garden trellis.

• Rectangular Drainage Pattern: It is found in regions that have undergone faulting.

• Radial Drainage Pattern: It develops around the central elevated point.

• Centripetal Drainage Pattern: It flows towards the central depression.

• Deranged Drainage Pattern: It grows from the disruption of a pre-existing drainage pattern.

• Orion is a well-known constellation that can be seen during winter in the late evenings. Orion is also called the Hunter.
• Tara Sirius is the brightest star in the sky. It is located close to the Orion.
• The International Astronomical Union (IAU) recognizes five dwarf planets: Ceres in the asteroid belt, and Pluto, Humeia, Mackemake and Eris in the outer Solar System
• Vesta is a famous asteroid. After the dwarf planet Ceres, the Westster is the second largest and second largest body in the asteroid belt.

Wular and Volat both are an oxbow lake formed by Jhelum and Volta river respectively.

Wular Lake, also known as Wolar in Kashmiri, is one of the largest fresh water lakes in South Asia. It is located near Bandipora town in Bandipora district of Jammu and Kashmir, India. The lake basin was formed as a result of tectonic activity and is fed by the Jhelum River and stream madhumati. Main source of water for Wular Lake is River Jhelum. This lake also has a small island in its centre called the ‘Zaina Lank’. This island was constructed by King Zainul-Abi-Din. Wular Lake is also said to be a remnant of Satisar Lake that existed in ancient times.

Volta River, chief river system of Ghana, formed from the confluence of the Black Volta and White Volta headstreams. The Volta flows generally southward through Ghana, discharging into the Gulf of Guinea. Its major tributaries are the Afram and the Oti (Pandjari). The river system has a length of 1,600 km, a drainage basin of 398,000 square km.

Both of the river’s two main upper branches, the Black and White Voltas, rise in the open plateaus of Burkina Faso (formerly Upper Volta) and unite in north-central Ghana some 300 miles (480 km) north of the sea. (These two branches are respectively called the Mouhoun and the Nakambe rivers in Burkina Faso.)

Hence Both 1 and 2 is correct.
