B is right answer according to Kalpakjian book.

Titanium can chemically bond with cutting tools, causing built up edges on the tool, decreasing the effectiveness of the tool. So option B is correct.

Titanium alloys due to their high strength, low thermal conductivity and chemical reactivity with tool materials (at elevated temperatures), pose a hazard to the tool and significantly reduce the tool life.

Answer is None of these. Because the titanium has very high strength. Due to low thermal conductivity of material, the heat is not dissipated from the primary deformation zone and chips gets accumulated thereby decreasing the shear plane angle and cutting force increases. This question asked in ESE 1992.

B is correct answer.
Reference: MANUFACTURING ENGINEERING AND TECHNOLOGY SIXTH EDITION by Serope Kalpakjian.
"Titanium and its alloys have very poor thermal conductivity (the lowest of all
metals), causing a significant temperature rise and built-up edge. They are highly reactive and can be difficult to machine.".
