सारणिकों के गुणधर्मों का प्रयोग करके सिद्ध कीजिए - `|(8,2,7),(12,3,5),(16,4,3)|`

Which of the following has value not equal to zero ? a) |(8,2,7),(12,3,5),(16,4,3)| b) |(1//a,a^(2),bc),(1//b,b^(2),ac),(1//c,c^(2),ab)| c) |(a+b,2a+b,3a+b),(2a+b,3a+b,4a+b),(4a+b,5a+b,6a+b)| d) |(2,43,6),(7,35,4),(3,17,2)|

Without expanding,find the values of the following determinants: |(8,2,7),(12,3,5),(16,4,3)|
