Given below are two statements:
Statement I: A series RLC circuit is said to be in resonance when current delivered by the source is in phase with the source voltage.
Statement II: Power factor of a series RLC is zero, if circuit is in resonance condition.
In the light of the above statements, choose the correct answer from the options given below:

A combinational logic circuit has three inputs A, B and C and one output Y. The output Y=1. when at least two inputs are 1. otherwise. Y=0. In its minimised SOP realization, the maximum number of two-input terms is:
