Show answer and explanation

Correct answer: (C) P-2, Q-4, R-5, S-3

Explanation

Newtonian fluid has a straight stress–shear-rate line through the origin(curve2). Pseudoplastic fluid is shear-thinning(curve4), while dilatant fluid is shear-thickening(curve3). The plastic-fluid curve5 has a nonzero yield-stress intercept. Thus P2,Q4,R5,S3 gives **C**.
