Match the antibiotics in Group I with the microorganisms that produce them in Group II.

The correct matching of antibiotics in Group I with the microorganisms that produce them in Group II is as follows:
- Streptomycin (P): Produced by {Streptomyces griseus} (i).
- Bacitracin (Q): Produced by {Bacillus licheniformis} (ii).
- Amphotericin B (R): Produced by {Streptomyces nodosus} (iv).
- Chloramphenicol (S): Produced by {Streptomyces venezuelae} (iii).
Thus, the correct option is ( {(P)-(i), (Q)-(ii), (R)-(iv), (S)-(iii)} ), which corresponds to option (B).
An electricity utility company charges ₹7 per kWh. If a 40-watt desk light is left on for 10 hours each night for 180 days, what would be the cost of energy consumption? If the desk light is on for 2 more hours each night for the 180 days, what would be the percentage-increase in the cost of energy consumption?
The \( F_{121} \) value of a known microorganism with \( Z \) value of \( 11^\circ C \) is 2.4 min for 99.9999% inactivation. For a 12D inactivation of the said microorganism at \( 143^\circ C \), the \( F \) value (in min) is .......... (rounded off to 3 decimal places)
Three villages P, Q, and R are located in such a way that the distance PQ = 13 km, QR = 14 km, and RP = 15 km, as shown in the figure. A straight road joins Q and R. It is proposed to connect P to this road QR by constructing another road. What is the minimum possible length (in km) of this connecting road?
Note: The figure shown is representative.
