46.

Assertion (A): Feedback control systems offer more accurate control than open loop systems.

Reason (R): The feedback path establishes a link for comparison of input and output and subsequent error correction.

49.
The addition of a zero to the open loop transfer function
pulls the root locus to the left and makes the system more stable
pulls the root locus to the right and makes the system less stable

50.

Assertion (A): For a given system only one of the static error constants is finite and significant.

Reason (R): If finite static error constant is large, the loop gain becomes smaller as ω approaches zero.
