If \[\overset{\to }{\mathop{a}}\,,\,\overset{\to }{\mathop{b}}\,,\,\overset{\to }{\mathop{c}}\,\] are three non-coplanar vectors, then the value of \[\frac{\overset{\to }{\mathop{a}}\,.(\overset{\to }{\mathop{b}}\,\times \overset{\to }{\mathop{c}}\,)}{(\overset{\to }{\mathop{c}}\,\times \overset{\to }{\mathop{a}}\,).\overset{\to }{\mathop{b}}\,}+\frac{\overset{\to }{\mathop{b}}\,.(\overset{\to }{\mathop{a}}\,\times \overset{\to }{\mathop{c}}\,)}{\overset{\to }{\mathop{c}}\,.(\overset{\to }{\mathop{a}}\,\times \overset{\to }{\mathop{b}}\,)}\] is:

• A. 0
• B. 2
• C. 1
• D. None of these
