Recently, the scientists at the Institute of Advanced Virology (IAV) at Thonnakkal have developed a novel way of generating non-infectious Nipah virus-like particles (VLPs) in the laboratory, which mimic the wild-type Nipah Virus (NiV). The Institute of Advanced Virology (IAV) is a research institute that is affiliated to the global to the Global Virus Network, located in the Bio-360 Life Sciences Park at Thiruvananthapuram, Kerala. Hence, statement 1 is incorrect.

It was inaugurated in February 9, 2019. Its primary aim is to conduct advanced research in virology and viral diseases. Hence, statement 2 is correct.

Recently, a groundbreaking study revealed that only 14-27% of the DNA sequences on ape Y chromosomes are similar to those in humans, indicating a significantly accelerated evolution rate for this male sex chromosome. The Y chromosome is one of the two sex chromosomes, with the other being the X chromosome. It plays a crucial role in determining male sex characteristics and fertility. Hence, statement I is correct.

The Y chromosome is originated from an ordinary autosome (non-sex chromosome) but acquired genes responsible for male-specific functions. Y chromosome DNA analysis is commonly used in forensic genetics and genealogical research to trace paternal ancestry. Hence, statement II is correct.

Here, statements I and II both are correct and statement-II is not the correct explanation for statement-I. Hence, option (b) is correct.
