B or d.... hope this helps:)
Answer:
The options
A. Additional cables
B. Slip rings
C. Multiple rows of detectors
D. Electron beam CT.
The CORRECT ANSWER IS B.
B. Slip rings
Explanation:
During the 1990s, the use of slip ring technology promoted consecutive rotation of the x-ray tube (via removal of cables) and concurrent couch locomotion.
The Sixth-generation CT scanning is referred to as helical (or spiral) CT—allowing procurement of volume multislice scanning.
Today's helical multislice scanners, makes use of thousands of detectors (around 60+ rows), can derive continuous data procurement of 128 "slices" per tube rotation and can undergo 3D multiplanar reformation (MPR).
Fifth-generation CT employs electron beam; as the ultra high-speed CT is employed majorly for cardiac imaging.

Explanation:
Studying animals in the wild is considered somewhat experimentally out of control because of several reasons.
<u>Explanation:</u>
Study of wild animals can be done using several methods but none will be as effective as studying captivated animals. Using stationary cameras is a method to observe animals in the wild. The stationary nature of the camera makes it necessary for the animals to appear within the field of the camera.
This is difficult in places of low animal density. In addition to that placing camera at a longer distance to watch a larger area decreases the resolution of the images. When it comes to shallow water systems, the field imagery used to track the aquatic species frequently gets affected by issues like sun flicker.
Unmanned aerial vehicles can also be used to track and study animals in the wild. This is good alternative but filming through dense canopies or turbid water is a limitation. Bio loggers can also be used for animal tracking but it is limited by weight since it has to be carried by animals.
