The right answer is C. Because the base of log is e in logarithmic decrement. So the LOGe =ln.

I think so that the answer is C because,
Logarithmic decrement = ln(x1/x2) = loge(x1/x2).
Logarithmic decrement = ln(x1/x2) = loge(x1/x2).

Yes the correct answer option is C. Because ::::: (x2/x1) = e^(logarithmic decrement).

C is correct,
Logarithmic decrement,
Delta =ln (Xn/Xn + 1).
ln = loge.
Logarithmic decrement,
Delta =ln (Xn/Xn + 1).
ln = loge.
