Consider \( 'n' \) is the number of lone pair of electrons present in the equatorial position of the most stable structure of \( \mathrm{ClF_{3}} \). The ions from the following with \( 'n' \) number of unpaired electrons are:
A. \( \mathrm{V}^{3+} \) B. \( \mathrm{Ti}^{3+} \) C. \( \mathrm{Cu}^{2+} \) D. \( \mathrm{Ni}^{2+} \) E. \( \mathrm{Ti}^{2+} \)
Choose the correct answers from the options given below:
(\( 1 \)) A and C Only (\( 2 \)) B and D Only (\( 3 \)) A, D and E Only (\( 4 \)) B and C Only
