The correct Answer is:
To determine which statements about paddleworms are true, let's analyze each statement step by step. ### Step 1: Analyze Statement A **Statement A:** "It is freshwater metamerically segmented prostostome." - Paddleworms, specifically from the genus *Capitella*, are primarily marine organisms, not freshwater. Therefore, this statement is **incorrect**. ### Step 2: Analyze Statement B **Statement B:** "The clitellum is absent." - Paddleworms do not possess a clitellum, which is a characteristic feature of some annelids like earthworms. Thus, this statement is **correct**. ### Step 3: Analyze Statement C **Statement C:** "Its larval form is Trochophore." - The larval form of paddleworms is indeed a trochophore larva, which is a common feature in many marine annelids. Therefore, this statement is **correct**. ### Step 4: Analyze Statement D **Statement D:** "It is unisexual." - Paddleworms are unisexual, meaning they have distinct male and female individuals. Thus, this statement is **correct**. ### Step 5: Analyze Statement E **Statement E:** "The nervous system is found in the epidermis." - The nervous system of paddleworms is not located in the epidermis; it is more centralized and located beneath the epidermis. Therefore, this statement is **incorrect**. ### Conclusion Based on the analysis: - Statement A: Incorrect - Statement B: Correct - Statement C: Correct - Statement D: Correct - Statement E: Incorrect The true statements about paddleworms are B, C, and D. Thus, the correct answer is **option C: B, C, and D**. ---

Consider a system of linear equation in three variables x,y,z a_1x+b_1y+ c_1z = d_1 , a_2x+ b_2y+c_2z=d_2 , a_3x + b_3y + c_3z=d_3 The systems can be expressed by matrix equation [(a_1,b_1,c_1),(a_2,b_2,c_2),(a_3,b_3,c_3)][(x),(y),(z)]=[(d_1),(d_2),(d_3)] if A is non-singular matrix then the solution of above system can be found by X = A^(-1)B , the solution in this case is unique. if A is a singular matrix i.e. then the system will have no solution (i.e. it is inconsistent) if Where Adj A is the adjoint of the matrix A, which is obtained by taking transpose of the matrix obtained by replacing each element of matrix A with corresponding cofactors. Now consider the following matrix. A=[(a,1,0),(1,b,d),(1,b,c)], B=[(a,1,1),(0,d,c),(f,g,h)], U=[(f),(g),(h)], V=[(a^2),(0),(0)], X=[(x),(y),(z)] The system AX=U has infinitely many solutions if :
