Correct Answer - B
Ans: B. Interossei and lumbricals
Hyperextension of metacarpophalangeal joint and flexion of the
interphalangeal joint is due to palsy of lumbricals and interossei
muscles.
The action of Lumbricals: Flexion of MCP, Extension of IP joint
The action of Palmar interossei: Adduction of fingers
