To avoid sudden collapse just after a shear crack, minimum shear reinforcement is provided in prestressed concrete member in the form of stirrups. IS 1343 suggested the relation as ________.

• A. \(\frac{{{A_{sv}}}}{{b.{S_v}}} = \frac{{0 \cdot 4d}}{{0 \cdot 87fy}}\)
• B. \(\frac{{{A_{sv}}}}{{bd.{S_v}}} = \frac{{0 \cdot 4d}}{{0 \cdot 87}} \times {f_y}\)
• C. \(\frac{{{A_{sv}}}}{{b.{S_v}}} = \frac{{0 \cdot 4}}{{0 \cdot 87fy}}\)
• D. \(\frac{{{A_{sv}}}}{{b.{S_v}}} = \frac{{0 \cdot 4{f_{ck}}}}{{0 \cdot 87fy}}\)
