Answer:
B. Lead guitarist.
Step-by-step explanation:
In a band, the member who plays solos that are often technically demanding and usually happen in the instrumental breaks is usually the lead guitarist. The lead guitarist is responsible for playing the lead melody and improvising solos during the instrumental sections of a song. They are often considered the centerpiece of the band's sound and are responsible for creating memorable and distinctive guitar riffs instantly recognizable to fans. While other band members, such as the keyboard player, bass guitarist, or vocalist, may also contribute solos or instrumental breaks, the lead guitarist is typically the one who takes center stage in this regard.
