Question 129/149

A data engineer is using Snowpark Scala to create a UDF that calculates the distance between two geographical coordinates (latitude and longitude) using the Haversine formula'. The function should accept four 'Double' values (latl, lonl , lat2, lon2) and return the distance in kilometers as a 'Double'. The UDF must be named 'haversine distance'. What is the correct Scala code to define and register this UDF with Snowflake, including the import statements required for using Snowpark functions?

A. Option A

B. Option B

C. Option C

D. Option D

E. Option E

Correct Answer: B

Option B is the correct answer. This code snippet correctly uses the 'udf function from 'com.snowflake.snowpark.functions._' to define the UDF using a lambda expression, making the code more concise. The 'haversine_distance' function correctly implements the Haversine formula. And the UDF registration is correct. Other options have incorrect import statements, register incorrect UDF, and specify 'returnType' within the 'udf function.
