Answer 1

The correct answer is:

(b) Tungsten

Tungsten is preferred for manufacturing microelectrodes due to its high melting point, excellent conductivity, and durability. These properties make it suitable for use in the fabrication of electrodes, especially in biomedical applications like recording bioelectric signals, where the electrode needs to withstand high temperatures and corrosion, while also providing accurate electrical readings.
