AReplaceable gib inserts
BCasing gear thrust bearings
CSpur gear adjusters
DReplaceable liner plates
AI Explanation
A) Replaceable gib inserts is the correct answer. In a lobe-type rotary pump, the replaceable gib inserts allow for adjustments to compensate for wear on the lobe edges over time. This maintains the clearance between the lobes and the pump casing, ensuring the pump continues to operate efficiently. The other options, such as casing gear thrust bearings, spur gear adjusters, and replaceable liner plates, do not specifically address the issue of wear on the lobe edges in a lobe-type rotary pump.
