• B. Surface tension is a vector quantity
• C. Renolds number is a dimensionless quantity
• D. Angle of contact is a vector quantity

Answer 1

Answer: (D)

Angle of contact is a vector quantity

Answer 2

Viscosity is a scalar quantity.

Hence option (1) is an incorrect statement

Surface tension is a scalar quantity

Hence, option (2) is a incorrect statement

Reynolds number is a dimensionless quantity

Hence option (3) is an incorrect statement.
